Debian is great but I can't say this is a shared experience. In particular, I've been bitten by Debian's heavy patching of kernel in Debian stable (specifically, backport regressions in the fast-moving DRM subsystem leading to hard-to-debug crashes), despite Debian releases technically having the "same" kernel for a duration of a release. In contrast, Ubuntu just uses newer kernels and -hwe avoids a lot of patch friction. So I still use Debian VMs but Ubuntu on bare metal. I haven't tried kernel from debian-backports repos though.
I’ve thought about (ab)using a Proxmox repository on an otherwise stock Debian system before just for the kernel…
