I love Edge, have been using it as my default browser since long before Anniversary Update.
Having said that, here's something regarding favourites handling in Edge I don't like.
At some point you will most probably re-install Windows 10 and before starting the process, you will export favourites, then after re-install import them. Of course if no favourites has been added since last re-install, you can use old favourites file without exporting it again.
If they change, new ones being added or old ones removed and you export / import them every now and then, the favourites menu looks stupid, to be totally honest. Here's an example from my laptop now, original favourites exported to file in April, I can't remember why I had to export again only a few days later, then again exported in June before my last clean install. Now, after a clean install on Wednesday, if I import that file again, it looks nested like this:

Luckily, the file is just pure HTML which means that you can edit it. I have too many favourites saved to manually move them one by one on top of the folder hierarchy when imported, I'd rather edit the file. I recommend you use Code Writer (available in Windows Store) or any other code editor that both colour codes and marks start and end of statements clearly.
Take the warning at beginning of the file seriously, only edit a copy of original file instead of the original one; a missing accidentally deleted comma might make the file unusable:

If you know your way around HTML, you can edit the definition terms and lists (DT and DL tags) in file (copy, not original. Better safe than sorry!) to remove nesting which is clearly seen in file:

I'm not saying you should do this every time you export favourites, I'm just saying that when the actual bookmarks you want to use are half a dozen folders down in hierarchy, you should at least think about if it would be a good idea to edit the list before importing it.
At least not before Q4, end of this year. It was clearly told that both bug bash as well as two webcasts last week were last ones before official release of version 1709.
