Regretfully my time for interwebz is about to run out, but to return to your original question:
Yes, I think this is an amazing upgrade! They have made some decisions I don’t quite agree with - like removing the audio-tab from the right-click menu for instance - , some decisions I had to figure out but very much appreciate - like moving the colours-editor to the top menus instead of a button - , and one dropped ball in still not having fixed the old issues with automation trimming, but as a whole it has made my life a whole lot easier, and contains a lot of really really nice things.
Regarding if it’s as great an upgrade for music as it is for post, then I can’t say for sure. I left the music industry completely a decade and a half ago in favour of movies and games, and only do music for fun nowadays, an Industrial Ethno-project I’ve been running since the mid 90’s, but…yeah, I’d still upgrade. No doubt. No clue if you’d consider it as worth the upgrade as I do or not, I know nothing about your needs right now so it’s hard to give actual advice here, but I do heartily recommend it.
