When you say SUSE, I assume you mean Tumbleweed? I’ve been on Leap for years but am skeptical of both their corporate and technical direction. I like the idea of rolling release but I’m cautious about the stability on my main daily computer.
But from my experience on Arch, all my pain from the rolling release model has mostly come from two sources
- Self inflicted pain from impatiance and poking things I should not be poking.
- Nvidia drivers.
If you want a "stable" rolling release, look into Clear Linux as well.
Open Build Service and Btrfs snapshots make for a very forgiving and stable experience.
