You just hit both of my points,
- Newer hardware has compatibility issues due to Ubuntu’s slower update cycle
2.ubuntu doesn’t do anything particularly better than any other distro, the marketing pitch normally ends up being “we’re Linux, and we’ve done it a while” because there isn’t any feature that makes it stand out so they advertise on their stability which isn’t that much more pronounced in comparison to a fedora or debian based distro.
What’s the problem with ubuntu?
In general I wouldn’t say it has a problem, it does what it says it will do, it’s just that it’s distinct features are quickly becoming the standard or obsolete.
I am unfamiliar with refind, but from my experience with systemd & grub dual boot, if you do not change your boot order in bios, there is a high chance that the windows boot manager will brick your Linux one, even across drives. My advice for dual booting is to ditch the convenience of using one boot manager. But once again, this may not be an issue you have.
