I run Gentoo as my main distro, and have for a couple years now. It’s a pretty stable rolling release (IMO more stable than Arch), and since you’re already an advanced user, the experience should be pretty rewarding!
The wiki is great, and the installation handbook is top notch.
You get to control exactly what features each package is compiled with, so no bloat at all.
KDE 6 just landed too!
Arguably Ghostbusters (1984) is prior art for throwing a capsule and capturing 🤣
Edit: they even had a video game with the ghost trap.
