Still Nightly builds are not as bug free as snapshot but still they are reliable that more users don’t mind facing small and few issues here and there in order to stay awaited for bug free CM 13.
It is recommended that if you are staying in CM 12.1 YOG4P or cm 12.1 YOG7D to stay on course with snapshot unless if you are ready to face some minor issues which means the quality of snapshot is higher than Nightly builds.
