Which distro?

I'm going to be building a new computer soon for myself. (Going AMD for the first time, since intel microcode issue.)

I would say I'm an expert or advanced user, as been using pcs for 25 years and set up arch and slackware in the past. I have tried many distros and would like some feedback.

I mainly use my pc for gaming. I want something customizable, KDE ish, and without bloatware. A good wiki is a plus.

I think that i may end up with arch... is it better for gaming since it's bleeding edge and isn't steamos built off it?

Side question is distro chooser accurate?
