Don't buy anything without putting your ass on it first. Everyone's body is different, and will interact with any given chair in different ways. Yeah, there's adjustability, but there's also some design choices that can't be adjusted around.

Me, I absolutely loathe the way those gamer racing seats squish my shoulders. In a car that design makes sense because the loss of comfort is worth the safety. At a desk it's pointless. OTOH for someone with a thinner frame it might be fine.

Go to a physical store and actually sit on some. Play with the adjustability and see what works and what doesn't. My current chair is a secondhand I-don't-know-what that cost me $50 at a thrift store and it's the most comfortable one I've had in years. Branding is overrated, especially when it's something as personal as a chair.
