Loaded it a few hours ago, was ehh about the start menu, but my classic shell synced up perfectly, cortana is interesting but until I get used to her the functionality seems kinda limited. I hadn't delved into the core of the changes yet, but on the surface it seems pretty decent. Edge the new browser looks very minimal which I appreciate but I need to tweak it. There's some very exploitable security settings I already altered to help cover, I recommend looking at your device sync options because they don't look very secure. I am having some shaky issues with my nvidia experience menu, looks like that might be common amongst other users, but I don't seem to have any compatibility issues. Direct Access options for enterprise users is apparently glitchy, I'm going to run a vm of it on a server tomorrow to see if I'm willing to update my enterprise setup but I might hold off until the initial exploits are discovered and remedied. All told, I haven't seen anything too revolutionary in this edition, it's honestly what 8 should have been instead of that garbage we were handed. If I come across anything else I'll update.
