Seems to be a lot of differing opinions here.I get the feeling what is your favorite to bet on is what you know best.For me it's the NBA. It's the one sport where I usually end up ahead.My local who tracks his players' plays for the season once told me I was the only customer who had a plus figure at the end of the NBA season with him.Really surprised me.It kind of shows you how hard it really is to overcome the bookie's odds in the long run.
