Distro hopping is what you do when you don't mind spending a week trying to get things "back the way they were".
You're not missing out.
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.

I'd always recommend trying things out in a VM before mucking about with your daily driver.
There is no benefit. You might like some other DE more or you might need some more recent version of some package but other than that, there is no reason to switch. But hey, have it both ways. Just install a few distros on VMs and see if you like those better. But basically, if your focus is on getting stuff done rather than tinkering and customising, Mint is absolutely fine.
Mint is basically Debian on easy mode so figure out if you're ready to change the difficulty
