Neither is "best" and no one can answer this question for you. You just have to try different diets to determine if any make a difference. Unfortunately, it takes a while to find out and if you change any other variables while you are trying you won't learn anything useful. Having been dealing with this since 1999 I can tell you that the ONLY way to find out if something makes a difference is to keep everything else the same while you're experimenting.
