From what I remember the dead rise is only 1 degrees more on the H2X over the Hammer. The Donzi on the other hand I think has a 24 degree deadrise like a true offshore boat. Forsure the Donzi is a well built boat but the 22ZX is a number of years older in design than the H2X and looks it if they were parked beside each other. We still have a 01 Hammer with a 454Mag Mpi and it runs 70 - 72mph gps. I suspect thoses two boats would be about 3 -4 mph slower under the same power. PS the H2X will lanch out of the water in the right conditons and be tons of fun. Good Luck!
