I drove a 2019 as well.. I also appreciated the extra "features" too.
- Fast info system
- Digital recorder with audio system
- Love the new look
- The ability to paddle shift 3 gears (can do that in the 2015 but only in Sport + mode)
- Rear heated seats
- Rear door unlock buttons
- Few other things
- (Didn't notice the tranny smoothness as mine is smooth)
At the end of the day the cost for a trade in and purchase wasn't worth it for me. But I agree Acura did a nice change.
