It’s definitely something that varies from person to person. I tried putting Graphene on a secondary Android device (an old Pixel 3XL) and compared to the stock ROM or more typical AOSP fork (e.g. LineageOS or Pixel Experience), I found it rather frustrating. I can’t imagine running it on my daily driver.

Similarly with Linux, the sheer number of rough edges, papercuts, and quirks is still too high (regardless of if I’m using a big name DE or hyper minimal tiling WM or somewhere in between) for them to serve as my main desktop environment.
