Bazzite is seeing an insane amount of growth right now
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

There's nothing wrong with Mint, it's solid. If it works for you don't stress about it
The only thing is that it's based on Ubuntu LTS so it's packages can be a bit old. Doesn't really matter much unless you have very new hardware and need the hardware support. Then something Fedora based like Bazzite would be better.
For getting newer software you can use flatpak/Flathub.
Bazzite is also "immutable" which makes it harder to break on a system level, but also harder to tinker on a system level. Mint is a "normal" distribution in that regard. Mint does have Timeshift for taking system level snapshots, on the off chance that an update or your tinkering breaks something. Its worth checking that Timeshift is set up for automatic snapshots
