Hey, great job first of all. In my opinion the B design is more effective.
(1) The verified button is contextual to the name whereas in A it's less obvious. I actually noticed it by looking at B as in A it looked like part of the picture.
(2) The follow / email action is grouped with information that can inform on the popularity of the user. If I look at someone interesting with a lot of followers it's much easier in B to find the follow action.
Depending on how important the actions are at the bottom I'd consider swapping the background with A.
Thank you for the feedback it's appreciated! Cheers
