I've been working on it for a bit, and it mostly seems ok to me. No crashes, and I haven't had any serious issues.
I do have an occasional issue where it will hang when switching from paper space to model space. It only seems to happen when I have imagery in the drawing, and turning off the imagery before I switch seems to address the issue. It doesn't crash, but I have to wait for a minute or two before the program responds again. But if I remember right, I had the same issue with 2017 until the first service pack came out.
I've heard (anecdotally) that a lot of people like to wait for the first service pack to be out before making the upgrade to a new version.
