Up to date mesa is in regular mint but only sort of. You have to manually go bleeding edge if you want by installing mesa drivers manually. Base Mint is a few versions behind on purpose, stability and I would say your kernel version makes a bigger difference in the end given how good mint is I recommend 6.14 kernel especially on fresh hardware, you can change your kernel version anytime in the update manager preferences, 6.8 is old but stable. 6.14 is newer, faster in gaming. Unless your on brand new, brand new released hardware this a non issue truly.

Most people will be fine with stock mint and you can't go wrong much with either. I game on stock mint full time! Windows only for BF6/dual boot. It's all I knew for several years was mint before going to NIXos and fedora and more.. My hardware is 7900xt 7600x. Full AMD on my rigs though I've built intel Nvidia.. I've built dozens of PCs/laptops/servers as I build and sell them. You honestly can't go wrong with either version but all I am saying is that if you hate bugs, updates ocassionally doing odd things especially to steam and proton. LMDE. I've been on mint for years this is just my 2 cents. I also value not fucking with my OS anymore I dislike command line memorization. I'm done tinkering and fixing shit all the time and prefer GUI or shit to just work ideally I'll trouble shoot for a few minutes then I stop, no more days tied up over dumb shit. With windows or Linux. LMDE is my choice. Best of luck.
