Well it depends what level you are on the perk. For example you can be a level 6 medic, but be a level 1 sharpshooter, so the "better" one would be the medic. To level up on a perk you have to do the requirements for the next level (like for sharpshooter you might have to get a certain amount of head shots).The higher level you are on the perk, the more benefits you get. if you are asking which perk is simply "THE BEST", I will just say which ever one you are the best at.
