Coming from stock and haven't had any other HU. So its a big leap in improvement for me.

Sound is good (but I'm not an audiophile).
CarPlay is an awesome feature (seems like any android unit can have this though)
iBus connectivity is great (again any android unit)
Reverse camera startup is fast
Form factor fits in single DIN slot, I only had to notch certain spots to get the brackets to fit. I could always restore the stock single DIN HU/OBC and CD player if I wanted
Cabling is great, didn't have to modify any harnesses
Customer Support is Fantastic quick to respond and very knowledgeable

Edit:
Steering wheel buttons also work.
Startup speed is okay
Orange Backlight seems to match with rest of interior lights well
Shipping was lightning fast. Preordered before release of Feb 26. Tracking started on Feb 27. DHL picked up the package (from Hong Kong) Feb 28. Arrived on my door (in California) on Mar. 1

Downsides:
Some of the buttons don't do anything? Hopefully I can figure out how to change them to different apps
