I have an Aeron at work. It's pretty good. But I have a steelcase Leap at home and I love it. Largely it's a matter of preference though.

My advice: look for something used or refurbished (although this is harder than before covid since so many people want good chairs now). I got the steelcase leap on craigslist from a used office supply store. They basically buy up furniture from companies that go out of business. When I went to pick it up they did a complimentary steaming for me. And it cost me $150 vs closer to 1000 new. The chair is about 15 years old, but Steelcase chairs are very well made and it honestly doesn't look more than 1 or 2 years old.
