Jump Desktop is good too. It can automatically adjust your Mac resolution to fit with your iPad which is an absolute game changer for my use case (just text work) which iirc Screens can't. I used Screens during the beta launch window of iOS 13 for a bit but it was super broken back then due to changes on Apples end, so I can't give a fair judgment. Eventually purchased Jump Desktop when it was discounted and have been happy with it, so had no reason to go back to screens. Not sure how either will hold up with your AE workflow though.
Nice! Do you happen to know if Jump Desktop supports, say, a Magic Mouse? The one thing holding me back from screens at the moment is that it doesn't support right click via mouse (and apparently crashes on iPad OS?).
