However over time you notice some things. First, it doesn’t let you sit incorrectly (like with your leg folded under your butt). Second, you can sit in in for hours (covid work from home situation) and be perfectly fine. Third, after 3+ years of ownership, it’s immaculate.

This right here. People expect to sit in an expensive chair and get a soft, plush, "comfortable" feeling. No, that's not what a quality chair is for. A quality chair's purpose is to let you be 40 years old, sit in it for an 8 hour workday, and get up at the end of the day with zero back pain (at least, none from sitting in the chair).

I forget how uncomfortable chairs can be until I travel for work and have to sit in something else for a whole day.
