Tony, glad you are "getting there".
The things I like are: drums and bass live sound, organs, pianos, guitars are great. Also Violin, Pedal Steel are very good. Saxs, o.k.
New interface is way better than the old one.
Vocal processing and harmonizer sound very good.
Lots of buttons and sliders for real-time control.

Things I don't like:
Placement of pitch bend wheel.
While the key bed is excellent, it isn't that well-suited for my style of playing. My bad wrist is starting to bother me after a few nights.
I'm thinking I actually prefer 61 to 76 keys. Go figure. I suppose it's from years of using 61. Now I have to look at where my hands are going, whereas I didn't before.
I would prefer it have OTS settings from the factory, although you can make and save your own to registration.
There are a lot more pluses than minuses, and it has been entirely stable. Audience response is very positive, but then it was anyway.
