EndeavourOS. It's a variant of Arch, I had hopped around different OS and was on Windows for a bit before switching back to Linux. Ive stuck with Endeavour as it feels quick and nimble but performs great on gaming (better than the native windows install on my PC) and the access to the AUR is a massive perk
Using Windows 11 with the StartAllBack program to make it look like a mix of Windows Vista (i like the look and grown too used to it back then ok!) and windows 7. Had a 10~ year old tower PC which i replaced with a Lenovo Legion 5 a few months ago, suoer happy with it!!
