Aluminum no contest the wooden bats are just to heavy and slow
Because Aluminum bats are hollow and wood bats are solid they have important characteristics for bat construction. If you want to make A wood bat longer (to protect the outside part of the plate) or fatter (to improve your chances of a solid hit), that means the bat must be heavier, which is a disadvantage. Not for an aluminum bat, because you can always compensate for the length or diameter by making the aluminum shell thinner up to a point. This flexibility in construction means that for a given length bat, both the weight and the balance point of an aluminum bat can be made whatever or wherever you like. This is an advantage for aluminum.
Since a wood bat it is solid, most of the weight is concentrated in the barrel, which means the center of gravity is further from the hands. An aluminum bat has a thin shell, so weight is distributed the same and less concentrated in the barrel.
Because of the way the weight is distributed, the balance point is closer to the handle for an aluminum bat than for a wood bat. Therefore an aluminum bat has a lower "swing weight" even though its actual weight may be the same as a wood bat. It is much easier to swing something when the weight is concentrated closer to your hands than when it is concentrated far from your hands. Therefore, a batter can often get a higher bat speed with an aluminum bat than for a wood bat of similar weight and dimensions. Higher bat speed generally means the ball comes off the bat faster. Moreover, the batter can propel the bat to a high speed more quickly with an aluminum bat than with a wooden one, allowing the batter to react to the pitch more quickly and even wait longer before committing on the swing.
The distribution of mass for an aluminum bat has a disadvantage. Because there is less mass on the fat part of an aluminum bat than for a comparable wood bat, the bat produces a less effective collision with the ball. For a given bat speed, the ball will leave the bat faster for a heavy bat than for a light bat. Even thought the total weight of a wood an aluminum bat may be the same, only the weight of the bat in the barrel is effective at turning the ball around and propelling it off the bat at high speed. A typical aluminum bat has less weight in the barrel than a typical wood bat and is therefore less effective.
An aluminum bat has a "trampoline" effect. That is, the thin shell actually compresses during the collision with the ball and springs back, much like a trampoline, resulting is much less loss of energy than would be the case if the ball hit a completely rigid surface. A wood bat is almost unable to be compressed and produces very little trampoline effect. The loss of energy comes mostly from the ball. During the collision, the ball compresses and wraps itself around the bat. It then expands back out again, pushing against the bat. This process results in much loss of energy. When a ball collides with a flexible surface, like a thin wall of an aluminum bat, the ball compresses less than it does when colliding with a rigid surface, since the thin wall does some of the compressing instead.
Because of the way the weight is distributed, an aluminum bat is more efficient at hitting an inside pitch. Another way to say this is that the "sweet spot" of an aluminum bat is longer than for a wood bat. This has definite advantages for miss-hit balls, that is, for balls hit off the main part of the sweet spot. An aluminum bat is more "forgiving"; that is, you can still make good contact. A wood bat is likely to break if you hit it too close to the handle. It has been said that college players, who almost exclusively use aluminum bats, have big problems making the transition to professional baseball, where wood bats are used, because of the advantage that aluminum bats have in hitting the inside pitch. In effect, college players making that transition have to relearn the proper ways to hit an inside pitch

Aluminum plus wooden bats break to easy.
