Personally I have my best return in College FB. I'm sure it has to do with the fact that I love the sport and follow it insanely close. I think all sports are equally as tough to pick and it all depends on the time you put in to it, especially watching games. Those who gamble are notoriously impatient and are always looking for shortcuts to profit. There are none. I have done unusually well here the last half of this NBA season and i know its because I have watched every game and every team i possible could since the midway point of the season. Like anything the more time invested the greater the return.
