Are there any stable/snapshot versions of any ROM that is Marshmallow-level?

Hello, I've gone from regular Samsung SG3 rom to CyanogenMod about 3 months ago. I at first was using their snapshot (stable) version, which was a CM 12.X. But I thought of being adventurous and switched to their nightly updates. That got me to CM 13.X, Marshmallow. Well, I'm finding a few problems with my use.

So I ask, are there other ROMs that have a stable/snapshot Marshmallow available. By "stable", I mean that all the bugs have been ironed out.
