I had to build some dev boxes for a couple engineers a few months before 18.04 came out, and I didn't want to build 16.04 just to rebuild them in 2 months. 18.04 was frozen and solid, so I built. They ran a bunch of engineering tools without issue.

I upgraded my 16.04 vm's to 18.04, and 18.04.1 is out so it super stable. Everything works.

Only thing different I did, uninstalled snap and installed spotify from a repo, but that repo has been giving key errors sometimes.
