Running recent AMD hardware and gaming. I have a ThinkPad Z13 with a Zen 3+ APU, a performance-oriented homelab machine with a recent Zen 4 APU, and a Zen 2 gaming desktop with a recent AMD GPU.
For the laptop, my main concerns are battery life, desktop responsiveness and gaming performance. As you may or may not be aware, the AMD space has seen a flurry of development activity these past couple of years thanks to Valve and the Steam Deck. There have been several improvements in the power management aspect in recent kernels, specifically the AMD p-state EPP driver. For desktop responsiveness, the new EEVDF scheduler has been a groundbreaking improvement over the old CFS scheduler. Finally, for gaming, there have been tons of performance improvements and bug fixes in the Mesa and Vulkan drivers, and as a laptop gamer I always aim to squeeze every bit of FPS I can get out of it. For some games, a recent Mesa makes a huge difference.
I also appreciate the improvements to the in-kernel NTFS3 driver since kernel 6.2 (where some important mount options were added) and most recently (tail end of 6.7) a bunch of bug fixes were also merged. I use an NTFS-formatted external drive for archival and file sharing between different machines (I also use macOS and Windows, hence why I went with NTFS), so any improvements to the NTFS3 driver is something I look forward to.
Next is my homelab setup, it's recent bleeding edge AMD hardware which runs a ton of VMs (Openshift container platform, Docker, Postgres and a bunch of web apps). When I'm working on it, I also use it for dev stuff and some work stuff - whilst all the VMs and containers are running in the background. So once again, I'm looking for stuff like EEVDF for desktop responsiveness, but also improvements to KVM or virtualisation performance in general. I'm also really excited for the upcoming kernel 6.9, because of the KSMBD and bcachefs improvements - particularly the latter, since I intended to evaluate a tiered storage setup using bcachefs, and if it's any good, I'll make the switch from btrfs.
Finally, for my gaming PC - obviously I'm always after the latest Mesa and Vulkan improvements, as well as overall desktop responsiveness and performance. In addition, I also care about things like VRR and HDR support, and all the Wayland-related improvements across the spectrum. All of which have seen vast improvements in recent times.
I mainly run Arch (with Cachy repos), which allows me to use optimised x86-64-v3/v4 packages for the best performance, as well as special AMD-GPU optimised Mesa/vulkan/vdpau/vaapi drivers which is available only for Arch (as far as I'm aware; but maybe there's a PPA for *buntu as well?). In any case, with Arch I'm able to easily fine-tune and get the most out of my systems.
So there you go, this is why I chase after recent packages and why Mint isn't suitable for me. I know if you wanted to, Mint users could subscribe to PPAs like Oibaf or something, or manually install recent kernels, but then you'd break the system and that defeats the whole point of Mint's focus on stability. On the other hand, I don't mind recommending it for someone who's main use case is primarily home-office/web browsing etc and they have an older system. But for power users, gamers, or those who have recent hardware, I definitely cannot recommend Mint in good faith.
