I used RISC OS at home. Was wonderful to come back to that.
Still love the old Acorn machines. I mostly use Arculator[0] nowadays for that nostalgia though.
There's a nice emulator here, a WebAssembly RiscPC one. Works quite well: https://rpcemu.m-h.org.uk/
Have you come across the Stardot[0] community yet? I feel like you'd enjoy it. Fair warning: it's more focused on the Acorn computers themselves (both 8-bit and 26/32-bit) than the continuing development of RISC OS. That said, I personally think it's great.
Same here.
Windows 2 and Mac System 6 at work, RISC OS 2 at home -- faster, more responsive, more capable and flexible, and much better looking.
Some of my friends had Amigas and to me, oh wow was AmigaOS 1.x fugly.
40 years later, KDE still is.
GNOME is beautiful but it's so limited it feels like trying to operate a mouse and keyboard with my feet while sitting on my hands.
COSMIC feels fast and powerful, but it is not easy on the eyes, and the keyboard UI is poor.

But when I was assigned an Ultra (1?) workstation at my first full-time job, I found that it was a better user and development experience to ignore it and use Linux on my Dell notebook, which I think was a Pentium MMX running somewhere around 200 MHz.
On FOSS side, I would vote for afterstep, windowmaker, original GNOME with sawmill, and KDE.
I wasn't a big fan of Windows 3.1 or Motif in their heyday, but compared to the visual chaos we have nowadays they're looking pretty good.
