The only difference it makes who drives your kart is the weight stat. If you have higher weight, you will be able to bump people around more. (Bowser can bump around yoshi because his weight is higher.) But, if you go off road with a heavier person, you will lose more speed. (If yoshi and bowser went off road, yoshi would lose less speed.) Of course, you wouldn't lose speed if you used a mushroom. I personally like to use lightweights, but the choice is up to you. If you don't know where to start, try a middleweight (Mario, luigi) and go from there.
