The Tyranids from Warhammer best the Zerg from StarCraft in any sense

Final arguments and statements: The Synaptic Web and "Shadow in the Warp" are two of the greatest weapons possessed by the Tyranid faction when dealing with Psychic/Psionics races and weapons. The shadow phenomenon is actually not irrelevant, the reason it does not cut off the Tyranids from the Hive Mind is because the Hive Mind is a physical being of psychic energy. When caught within the bubble of a Hive Fleet where the Shadow of the Warp takes place, Pyskers/Psionics are hit with a wave of psychic energy, using their abilities in any way allows the Synaptic Web to touch the psyker/psionic, which results in the millions of instinctual thoughts and psychic chatter of the Tyranid force being heard by the individual tapping into it, it creates a pain that is as unbearable as being a survivor during the Tyranid aftermath where they mop up the remaining biomass. The only reason the Zerg would be cut off is because of the alternative and more immediate presence of another Hive Mind in the vicinity, a creature whose influence spans numerous galaxies rather than a few star systems. In this sense, the Primal Zerg would be the best defence against the Tyranid invasion. If a counter to such a phenomenon exists to help keep the Zerg forces under control, then I suppose at that point, it's a battle of strength. Synaptic Tyranid forces do not possess the ability to link to non-Tyranid forces, linking with them however is suicide in its own right, they are the physical embodiments of the Hive Mind, a being of pure psychic energy who connects all Tyranids, if more info existed on him and Kerrigan's true and full power, then that would be a discussion of another day that would be well worth the talk. However, at this point, it would be impossible to tell if the Hive Mind would destroy Kerrigan's mind or it Kerrigan could withstand its psychic backlash and attacks to take over some Tyranid forces. Since a lack of evidence exists no matter where I look, I would like to say that at this point, it comes down to a test of strength. Zerg forces are the ones being attacked here, so yes, the Creep would allow a quick response time to Tyranid invasion forces. That is where the most interesting point of the conversation would arise... Since Tyranid invasions begin at a center point where a cluster of mycetic spores land and vomit the first of the Tyranid forces, would the Tyranids be able to establish a beach head? Or would every impact zone be overwhelmed by Zerg? If a faction that was very unlike the Tyranid and Zerg were the topic of conversation was the one invading, then I would say yes. However, in the case of the Tyranids, the sheer speed at which they mobilize and begin attacking would allow a beachhead to be established. While Zerg are more sophisticated by the individual and strategies do exist among the Cerebrates and Kerrigan, the Tyranid way of fighting is "Quantity is its own Quality", this is the quote that best fits the Tyranids because they deploy and attack in such large forces. One mycetic spore can house hundreds of Hormagaunts whose tenacity and resistance to faltering under pain would result in a shock on Zerg forces. Zerg units are not instinctual monsters like the Tyranids, they can think, they can collaborate, they have a hierarchy. However, in the case of the Tyranids, the lack of one is its own benefit. This being because Tyranid forces are given but one instinct to act upon, Hunt, they do not retreat, they do not stop to rest, they do not defend areas of value. In this sense, the very shock and awe of their entire military is enough to throw Zerg forces off in the beginning of a battle. Soon, I am sure the Zerg Queens will surely attempt a psionic link with the Extragalactic forces, however, even if a Queen were to bypass the pain and horror of the synaptic web, they would find that the Tyranid forces are nothing but animals who are sensitive to Psychic energy. Not sensitive as in susceptible, sensitive as in, they can find it faster than anyone else and they hunt it. Synaptic Tyranid leaders would surely be deployed after the beachhead is secured, this would indicate that more Tyranids are currently en route to the surface of the planet, since Tyranids work like an explosion, meaning, the front lines attack attack attack while the smaller wormlike ravagers consume the biomass in conquered land. The large amount of Creep and bodies, both Tyranid and Zerg, would allow fast propagation of the Tyranid forces during the fight. Seeing as how in every battle the Tyranids fight in, their forces seemingly double at the very least during a campaign, and increase dramatically after all resistance has been dealt with. No doubt, Zerg forces would need to adapt to the oncoming hordes of more dangerous form of primal animal, one that seeks nothing but to consume and grow rather than become omniscient and perfect. Adaptations on the Zerg side would, in my mind, be mostly armor and weapon strength based, allowing Zerg forces to withstand the rending claws and scything talons of the Tyranid forces and also be able to cut through whatever chitin armor the Tyranids bear. After a synaptic Tyranid witnesses this, the memory is sent to the Norn-Queen aboard the largest and most defended Bioship and she begins making new strains of Tyranid forces. This is where the adaptations and counter adaptations exist. However, Zerg forces can only adapt so much before their genetic strain cannot be modified or stretched any further. The Zerg only seek out specific DNA to assimilate, only the most beneficial so that they can reach perfection. The Tyranids take everything and utilize everything, Zerg forces would reach an evolutionary deadend quicker than the Tyranid forces would, this would be the turning point in the counter adaptation point in the war, eventually, Zerg forces would no doubt begin producing ultralisks, the giant scythed behemoths that kill everything. This would only spell disaster for the Zerg, Tyranids send forces in response to an adapting foe, this is where the Bio-titans would arrive. Tyranids the size of the Tallest Sky scrapers would arrive, bearing weapons that bristle all over their bodies. Hive crones would assume complete air superiority once the scourges and mutalisks become a nuisance to the Tyranids, and the frontlines would be pushed back. Eventually, there will be so much that happens that no real strategy that exists could stop the Tyranid advance. If the Zerg were fighting a foe that relied on any resource besides biomass, then tactics to hinder supplies could be taken. But the Tyranids seek any type of living or life giving material and utilize it in their propagation, the dead would fuel the Tyranid advance and the surrounding Creep and living Zerg buildings and ecosystem would be devoured. The Zerg have a self preservation where the Tyranids do not, Kerrigan is smart and powerful individual indeed. But what could she for the planet that is currently under attack by Tyranids? In any universe where either of these two exist, there is a constant state of war. Kerrigan's Zerg worlds would bear the forces capable of reinforcing and fighting back the Tyranid Hive Fleet, but is she really willing to pull Zerg units out of positions on key locations just to keep a planet that was being consumed during the war? Even Kerrigan knew when and where the fights that were worth it existed, and I say that Kerrigan would rather save the remaining Zerg forces and make an escape than to continue a war with a force who has more different types of weapons than she does different types of Zerg. Even Kerrigan would understand that the only real way to defeat a force of nature built on war would be to have the entirety of the Terran and Protoss races unify with her and fight the Tyranids. A few races in the WH40K universe know that unification is the only way to truly defeat such a foe, but unification is as far fetched an idea as defeating the Tyranids. I await my opponent's final argument.
