Actually, when it is stated a version is more stable than an other, that really means the version was more thoroughly tested, not that the other version is unstable by design. Usually the newer versions include bug fixes so the later the better. Newer versions contains also new implementations or new features, and the risk is here, but still low.
I run mostly community versions, and I upgrade when some new appealing feature looks good to me. As I wrote, I never had a kernel panic or data loss due to the O/S beta status. Of course the is some risk running unsupported software, but that's fine with me. I'm not running a nuclear plant or similar critical applications on my laptops and PCs
