What NHL game have you played last? I think that will factor into it.
If you're a BaGM guy, then go with 14 (that is, if you're trying to decide with another NHL title), it is the most advanced.
Third person fighting is definitely better, but the "enforcer engine" needs better implementation. In reality, it's the best thus far but, I was a little disappointed in how it comes into play. Still, it's not a hindrance.
The progression system isn't broken, it's whether you like/agree with the design of it. It's been tweaked through a patch and more people are accepting of it but, in all honesty, I thinks it's the best they can do based on the player rating system already in place. I mean, I like things very realistic, and I think they've tried here but, be careful of the "real life" logic you use to interpret the outcome.
Gameplay? This is the tricky one. I think most people are upset because they expected more in '14. They wanted big changes and that didn't happen. If you're going to be playing BaGM, I would say you're going to wind up on superstar level at some point (if you're not there already), due to the lack of defense on the cpu's part below superstar. However, you're going to need a great deal of patience playing defense on this level. I've wound up playing more like the cpu: going with the play and waiting to make a move.
I have a dynasty blog for my BaGM with highlight videos. You can check it out here:

Maybe you can get an idea of the game play against the cpu.
