Ah, good question! It was hard enough to answer back then when I made Quersus VS DXRacer, but now… It’s hard to answer without doing a full comparison of the two brands, with their faults and advantages. Secretlab’s advantage over Quersus is that they have a particular chair model, which like Quersus comes in different sizes. But they have gone one step further in terms of adjustments and functionalities, with a magnetized headrest for example, or a lumbar support adjustable in volume AND height, which is not yet possible with Quersus. For the time being, Quersus only offers volume-adjustable lumbar support. There’s also the option of tilting the backrest, which is much more advanced with Secretlab. However, Secretlab’s prices are much higher than Quersus’ “normal” models (by which I mean with the exception of the ICOS, basically). However, Secretlab don’t have any chairs that, like the ICOS, allow you to adjust the depth of the seat. So I’d conclude that it all depends on your budget and what you’re looking for/on which you’re willing to make concessions or not. The Secretlab is one of my top gaming chairs.
