You won’t regret it.
But be aware, it is an immutable distro. This means that it is basically unbreakable (you hear stories about how linux machines can become broken by some update or such, but not bazzite or other immutable distros).
But this also means that if you don’t find an flatpak (or appimage) of a program you need, it can be a little teadious to install it.

Just a warning. The distrobox option is especially flexible and powerful, but you do need to do a little reading up and setting up to install stuff using these methods.
Otherwise everything on bazzite JUST WORKS, especially gaming. And the flatpak store has a ton of stuff, I have never needed anything that wasn’t on there.
Yes, they are dominating the handheld gaming market and will continue to do so for a while.
This has nothing to do with your personal preferences.
