EndevourOS is excellent. It has been very stable for me. It is easy to install. Your problem will not be out of date packages for sure.
That said:
- there is no graphical package management. You will need to use command line ( yay / pacman ) or TUI ( pacseek ) tools.
- there are A LOT of package updates and you will want to stay current with them. I update my packages multiple times per week.
If either of those things bother you, they may be a problem.
Updating packages is reliable and painless but a chore you need to get in the habit of doing. I suspect you would get more problems if you let it go too long. On the upside, as it is a rolling release, you never have an “upgrade” to go through.
