I've had both aluminum and fiberglass. All my aluminum boats' (SeaArk; little V and Xpress; flat) welds cracked in Big Lake. In a 2 ft big lake chop, I would travel 8 mph because the your teeth and bones are rattling. My fiberglass bay boat will hit a 2 ft chop at 40+ mph with little discomfort. Aluminum is fine as long as the water is smooth.

It depends on the design of the hull more than it does the type of material it is built out of in my opinion. If its a flat bottom it doesn't matter what it is built out of its gonna be a rough ride. The more v it has the better it will ride but also too much v will take away from its shallow water capabilties. You just have to find what's best for you.
