Used it already for a short-time production with EEVEE for a stage show. Stability was good enough, though 2 or 3 crashes during production. But if you save regularly it’s no problem at all.
For the VSE I still stick with 2.79b, because I have still more confidence into the fast paced work flow and stability.
Started sculpting with 2.80 to get used to it for the future, some things are different (for example background images in 2.79 and 2.80, use of tablet and so on). Modeling feels like no big differences between 2.79 and 2.80.
I like the tabs for changing different working areas with their specific settings, it helps a lot. And start to miss some new features in 2.79. With the announcement of the release in the near future it does not really make sense to me not to use 2.80.
But could be different in a tough production pipeline. If you want to be on the safe side you better wait for the first bug release after 2.80 (2.80a, 2.80b) or better for the 2.81.
