I've owned both.
H2X is a great lake boat, but with a shallow deadrise it doesn't ride as good in rough stuff as the 25 O/L.
H2X is a fast, fun boat to drive. Actually, so is the 25, but the 25 with a 24 degree deadrise will cut through the chop better, and is a heavier boat so will ride better also. But both boats are excellent boats.
The 25 will be a little slower than the H2X with the same power.
I wouldn't own either boat with a 310hp 7.4. You want a mag or better, and prefferably a 502 mag or better for the outlaw.
Personally, I like the bolsters on the 25, although there is not quite as much room in the cockpit of the 25 as there is the H2X. The cuddy is larger and easier to ingress/egress on the 25.
In summation, both are great boats as far as I'm concerned.
