Kylo Ren is the weakest Sith of the 5 main (listed) Sith Lords

1) Kylo vs Vader"Kylo is in far better physical shape and has a crossguard lightsaber""Vader would have trouble finding the willpower to kill a family member and resisting his lightside"- A Crossguard Lightsaber provides minimal advantage in a fight against an experienced foe like Vader. It didnt help Kylo at all when he got whipped by Rey in Ep 7 and it most likely will have no effect in a fight with Vader- Vader is Kylo's literal idol, it would be almost impossible for Kylo to try to kill Vader even if he was at Kylo's complete mercy since Vader's legacy is the main force driving Kylo to be a Sith - Vader tried to kill his own son throughout the first trilogy, and Vader even killed both of his mentors (Obi-Wan and Sidious) who were family-life figures to him in his life. Vader would have minimal issue killing Kylo just because he is his grandson, the span of a rebel leader and a mercenary who both opposed the dark side. - In Ep 7 it is revealed by Rey herself that Kylo's deepest fear is never becoming as strong as Vader and that he struggles to resist the light side as well. 2) Kylo vs Sidious"Ren used the force to hold still plasma energy fired from a blaster rifle in flight. He could use a similar force move to block force-lightning"- It is unfounded speculation that Kylo could stop force-lightning just because he managed to sotp a plasma blast, so it cannot be treated as fact that he could also stop force lightning- Sidious can fight with a lightsaber as well, having fought off Yoda in Ep 3, killed several other Jedi in Ep 3 as well, and killed Mace Windu after getting an assist from Anakin/Vader. Sidious is very capable of killing experienced Jedi, Kylo does not- Kylo is mentally weak and can be manipulated by others, and Sidious is the master of manipulating people to do what he wants. In a fight between Kyo and Sidious, Sidious would easily be able to weaken Kylo with mental tricks before finishing him off. 3) Kylo vs Dooku"Ren again would just cut off his hands like Anakin did. Ren has the advantage of a crossguard lightsaber."- Again, a Crossguard lightsaber would have minimal effect in a fight against an experienced Jedi- Dooku fought off attacks by Obi Wan, Anakin, and Yoda in Ep 2 before being brought down by Anakin in Ep 3, making him 3-1 in Jedi fights. It would not be simple for Kylo to 'just cut off his hands' as you imply- Dooku is also capable of force lightning like Sidious, and it is disputed whether Kylo could stop force lightning or not- Dooku is also known for playing mind games, which against a mentally weak foe like Kylo would prove advantageous to Dooku4) Kylo vs Maul"Ren can mind-read, force sense, and telepathically torture people""Ren would win as he has demonstrated in Ep VII to a much more adept Force user than Maul.""Maul also has the disadvantage of wielding a two-handed lightsaber""Therefore, unless Pro can demonstrate that Maul can influence galactic events in the same ways Dooku, Sidious, Vader, and Kylo Ren can"- Kylo can only use torture techniques on people when they are heavily restrained and at very close distance. There is no indication he could do the same thing at a distance against someone who is unrestrained or is a powerful Jedi- Kylo himself admits that there is still a Light in the force within him that he cannot distinguish. He therefore does not have any kind of force advantage over Maul since the force within Kylo is tainted to begin with. - A 2 handed lightsaber is NOT a disadvantage, and to claim that it somehow is is ridiculous on con's part. It is very possible to wield a 2 handed lightsaber with one hand, and Maul did that several times in Ep 1- Kylo CANT influence galactic events the way Sidious or Vader can, Kylo answers directly to Snoke on all matters and is just a pawn for Snoke to play with the same way that Maul is a tool at Sidious's exposure. 5) Other arguments"Most evidence actually suggests that Kylo Ren was trained by Luke Skywalker"Ep 7 clearly states that Kylo is still unfinished with his training, as admitted by Snoke, Kylo's trainer, himself"Kylo Ren is by default one of the most important force characters in the star wars universe."Doesnt matter. Only one of Kylo's parents have any Force qualities to begin (Leia) with while the other denied the existence of the force in the first place (Solo). Vader on the other hand was the original chosen one meant to bring balance to the force, indicating that he and every other Sith Lord are not at some sort of 'Force disadvantage' to Kylo just because Kylo is the nephew of Luke. "Ren has the mental perseverance and obsessions of an Olympic Athlete"By your own admission you admit that Ren is mentally weak who gives in to anger and frustration very quickly. He is therefore NOT an Olympic Athlete in terms of mental strength like you claim."unless it can be proved that the other Sith Lords are more influential to the fate of the galaxy than Kylo Ren, Ren cannot be considered the weakest Sith Lord in terms of power."I only have to argue that other Sith Lords are at least equal to Kylo in terms of influencing galactic events, and then point to other qualities about the other Sith Lords to show that they are still more powerful. I have done exactly this as well. "Kylo has no clear losses to his name"He got whipped by Rey and was left to die on Starkiller base as the planet collapsed, that qualifies as a lossIn summary, Con has provided several arguments that are unfounded or are directly contradicted by earlier arguments he has made. Kylo is mentally weak as a person vulnerable to crafty opponents like Sidious or Vader, Kylo has not completed his training as a Sith either, and Kylo is not more powerful than any of the other four Sith I have listed, whereas Con has tried to argue that he is more powerful than ALL of them. All previous arguments indicate that Kylo is the weakest of all the Sith Lords listed, not the strongestVote Pro.
