I usually wait a few weeks, but had to upgrade this time for the XCode update and News Preview sim plugin and I had the same experience—even on both an 13" 2013 MBP and 15" 2015 MBP. No problems, but no noticeable changes, really. Except for the font... I use Notes as well and I guess I like the new features, but I hope it doesn't go much further.
