Cachyos is great if you want access to everything, debtap for the rare ocassion you need to install a deb, can install snaps and flatpak support easily, but you don't really need to mess with all that, mostly everything is available with aur + flathub (have to do one terminal line since cachyos doesn't have it by default)

Bazzite does have bazaar by default, which i like as the best flathub appstore, aur version stopped working for me.
