I've been using CentOS for several years. The down side (for me) is having to reload the OS every 3 or 4 years. I've only recently tried a rolling release, Manjaro. I've been using it for about a year. I haven't had any major issues. It has had a few flaky moments, but all in all not too shabby. I will say that flipping back and forth between different distros on a daily basis can be a bit flustering at times remembering subtle nuances between them. But... I wouldn't have it any other way.
