If you try the installer, be careful when selecting multiples DE/WM as the conflicts were not listed anywhere for the installation process.
Picking a single environment and then adding the others later was what worked for me.
Pretty much everything. Seperate package repo shipping cpu modern optimized binaries, custom kernel, and a ton of gaming and preformance related patches applied ontop of various packages. As well as a gui installer.
