My best middle ground is openSUSE tumbleweed. It is a rolling release but very reliable. Its not bleeding edge. It has snapshots which function like very small stable releases every few days insteqd of every package being updated individually. Every such snapshot has automatic testing. So all in all, very stable for a rolling release.
Not a huge fan of rolling releases but Ubuntu/Debian are too far behind, Fedora is a very nice middle ground.
