No it doesn't. It will ride a bit "stiffer", though, for a hull built to a given strength, as an aluminum hull will be lighter, hence less mass to displace the water.
Aluminum advantages: lighter weight (makes a difference in trailering), minor damage usually requires no maintenance, very little upkeep (assuming a decent alloy is used in construction), any major repairs are usually a welding shop away. I personally think that a well built plate alloy boat is much stronger than a glass hull, but we're talking about catastrophic impact here, so that may not be a selling point. Small repairs, while not tough, may be more expensive to perform than similar damage to a glass boat (i.e. less of a DIY thing, unless you are a welder. I just leave it be.) Small flaws usually are much less of a problem (no water seepage into cores, and resulting rot problems, for instance.)
Aluminum disadvantages: Cost (with a capital C), possibility of galvanic corrosion, limited forming methods may mean a less appealing shape (subjective), may be more difficult to find bottom paint (for those who moor their boats), painting (topside) requires a lot more care to get paint to adhere. In my case, you get a lot of people asking about the cost, and why I paid more than I would have for a glass boat; which gets kind of annoying after a while (getting out on the water helps quite a bit.)
Either can be quite good, or, I would assume, quite bad, depending on circumstances. For me, the durability of aluminum in day to day use is what spurred my decision.
