Chances are you haven’t had one style of haircut you’ve stuck with your whole life, so why do that with your face. You don’t have to stick to one shape of beard for all eternity; you can and should experiment. Maybe you want to have a longer mustache and shorter sides, or vice versa. Maybe you want the base of your beard to come to a small point, or maybe you want it rounded to perfection. Or, maybe you just want to experiment with varying lengths of hair. The point is, you won’t know what shape you like most until you experiment with your beard.
