Didn't want to create a LTTP thread so I thought it would be ok to post in here.
I just finished the game thanks to the free EA access week. It's pretty good to be honest. It improves stuff from the first (melee combat, and the writing), while keeping the (mostly) good parkour controls, the clean art direction and the good level design.
Obviously the biggest change is the open world aspect and the ability to choose the order of missions and optional stuff. I didn't mind, but the city does feel fairly small and repetitive after a while, especially if you start looking for collectables. But it's not the catastrophe I read about at release, the game is quite solid and has a good length without being too long.
There were a few technical issues on Xbox One, like a level getting all dark at some point, or some texture flickering. It still looks good and the 60FPS is great. Too bad not everything is 60FPS, the drones and the cars for example are 30FPS I think. But those things have happened only a couple of times, so no big deal.
Overall I enjoyed it.
