Choosing the right birth control?

ε

I'm currently not on birth control, but I will be going on it soon. I'm purely getting it for birth control. My periods are regular, my cramps are fine, everything else is fine. I also have really good skin (I'm lucky). I'm going to ask my gyno about the different types, but what's the best choice for me if I'm not trying to gain much weight, or get acne, and it's purely for birth control? I know it all varies from person to person, I'm just curious and hoping I could get a little more information from others because I'm clueless.
