I use EndeavourOS because I like having access to the AUR but didn't want to risk messing up my Windows installation by trying to manually set up Arch for dual booting (this was before archinstall was made). I like it, and I like using KDE. My only complaint with it would be that pacman kinda shits itself if you go too long without updating.

The first distro I ever used was ZorinOS back in like 2017.
