Ok here's my experience with them thus-far.
I played 6 pick up games total. 3 in the Attack Fast. 3 in the Attack Strong. I wore some Nike Elite socks and didn't have any blisters or anything like that.
Attack Strong:
The fit on my ankle was great. Had some really good support and stability in the ankle. As expected, it limited some cutting and movement, but not as much. Played in the post quite a bit to see how much stability it would give with footwork, and it held up really well. The comfort level was really amazing on these.
Attack Fast:
As KobeoverLebron stated, after playing in the Attack Strong.. going to the attack fast is tough. It's definitely lighter and allows more lateral movement quickness. Ankle support isn't as strong of course but it still provides stability.
Honestly, I feel if your a post player, the attack strong is a good fit for you. I always thought Kobes would be a strictly guard-oriented shoe but the attack strong may make a strong case that this is a shoe for post players as well.
On another note, I think my zoom air may have popped... hopefully that is not the case b/c I'm very impressed with the shoe thus-far...
