It hasn’t hit the official release yet, but I would. Otherwise you’re learning an interface that’ll go away in a month.

One benefit of 2.7 is that there are a more preexisting tutorials out for it, but 2.8 is getting quite a few as well.

I haven’t been following too closely on what the best new tutorials are, but I saw some linked here the other day: https://reddit.com/r/blender/comments/by7ejt/having_bounced_...

It's still in beta with a release slated for July, but yes.
