Aeron is largely considered THE best office chair from all I've seen on it. Way out of my price range, even if I could technically swing it, I use standing desk / treadmill / sofa too interchangeably with sitting for it to be worth investing in.Are both good chairs?
I really like my $200 IKEA chair though, after I got better wheels on it (it was only like $140 when I bought it a couple years ago, yikes): MARKUS Office chair, Vissle dark gray - IKEA
