My two cents is that it depends. And that can be the answer for a ton of MBA questions. I think any MBA can open doors, the question is, how far does the door get opened, and how hard it is to completely bust through the door. Obviously, the better the program, the more the door opens and the easier it is to follow through.
Another consideration is, are you being sponsored by your current company. If your company wants you to get an MBA and they will bump you up their ladder because of it, any school will do.
Again, that's all just my opinion.
