Windows 10. The reason I switched was pretty funny - I had previously bought a cheap SSD and moved my install over to it, and installed Arch on my HDD hoping to experiment with it.
I never really did that, but one day before Christmas my computer booted straight to Arch to my confusion, and after a while I figured out my SSD failed. I ended up installing gnome to have something to use in the meanwhile, since I wasn’t gonna be buying a new SSD in the next few days, but then I just decided to stick with Linux. As I learned more about it I realised I was barely missing anything, and I preferred Linux for what I had.
Mind you, emoji were created in Japan, so a lot of the original ones can be weird to us due to cultural differences.
