It is a common misconception that rolling release distros are inherently less stable than other distros. My experience has been exactly the opposite. I've used, for extended periods, Ubuntu, Manjaro and Arch. Both Manjaro and Arch were far more stable than my experience with Ubuntu. With ubuntu, every time I had to do a full system upgrade it was a crapshoot about whether or not I would be spending the next day or two fixing my system. But with Manjaro and Arch, it's never a full system upgrade, as long as you are doing updates regularly, they tend to remain small and manageable.

I've never had an update brick my system on Arch and have never felt the need to restart from scratch because an update went to shit. But that was an experience I was getting used to on Ubuntu.

Disclaimer, this is just my experience, and your own mileage may vary.
