I use a zero gravity. Specifically, MWE labs. Downsides were taking it apart to get it to my second floor home office. Upsides are comfort and not getting pain from working long hours. I've owned for over 2 years now. I don't use the zero gravity aspect of it a ton, though. It's still worth it in my opinion for the ability to make micro adjustments and overall ergonomics.
