I have the Dota 2 one. It's quite nice and is well worth the money. I work from home quite a lot, and this was the first time I got a non-cheap chair. It is a """gamer""" chair, but it's quite comfy IMO and has a ton of adjustment options. You'll find the adjustment options in many high-end chairs like this one though. A popular one I hear is Herman Miller chairs, so I would definitely check those out.
My wife also bought a Titan as she is working from home recently. She just got the plain one, but she loves hers as well. She had a cheap chair before that was incredibly uncomfortable, but didn't know because she hadn't sat in it very long until now due to the lockdown.
