P90X, Insanity, or asylum, which is the best way to lose fat and build muscle?

im not really high over weight but i have annoying fat on my stomach and other parts of my body. my muscles arent really that small either but im trying to get bigger and build more strength. which of the three programs (or a hybrid of them) is the best for my goals. also, if you know a better program that works let me know.
