@mischievoustomato same deal as usual, I just installed it and it did what I needed it to do, which was no systemd by default and a very clean KDE install. I also like how you can customize it (make.conf and use flags).
Oh, and this is just a personal thing, but since gentoo is a meta distribution you can fit it just about anywhere gcc/clang can compile to. I've installed it on old ultrasparc II sun workstations and tiny little chinky risc-v boards. Its very straightforward once you figure out what you're actually doing with it.

For (you) specifically:
- Binary packages (repo already set up with the latest stage3 tarballs)
- Binary kernel (gentoo-kernel-bin) so you dont have to play around with customizing your kernel, which is the hardest part of installing gentoo imo
