Honestly Arch-based is a good choice, but straight up Arch for a newbie? Nah.
I’m running EndeavorOS with KDE and it’s been solid for gaming. A few bugs, but mostly minor, like it picked the wrong default NIC driver (but still worked) and SMB shares wouldn’t auto mount recently until an update a week or two ago.
My main PC for non-gaming runs Manjaro. I know there are haters about it, but it’s been a solid distro for general use, and I’ve encountered no issues to speak of.
Don’t waste your time. It’s honestly fucking awful. Reading it was like experiencing someone mentally masturbating in real time.
