Personally I really enjoy it. Phantom liberty (and the patch to the normal game) adds a new area that is basically a microcity in itself, with a really fun side story that even adds additional endings to the main game.

No story spoilers ahead:

The update also brings a lot of randomized content that helps making the city feel much more lively, for example you will encounter random gang shootouts or car chases, or if you pick on one gang enough they will hunt you down as well. The police is a lot more dangerous, and continued resistance will eventually earn you a visit from maxtac. They also got the city transit system working, you can ride by train from a to b if you want while enjoying the view.

Also, assuming you didn’t play at all since the 2.0 overhaul, they completely reworked the talent trees and skill paths, making them much more distinct and all around fun to play with. The loot and difficulty system is also overhauled, and will mostly scale to your level regardless of where you are in the story, giving much more freedom in what you want to do and when.

Then there is vehicle combat of course, with a wide range of armed vehicles to obtain, which is also pretty fun and useful.

Generally it feels much closer to what was promised. It might not be perfect, but it is in a fantastic state in my opinion, the only thing I really miss at this point is the holy grail of third person camera (with a working player model).
