I think the Hughes/Northstar boats are decent, S&S designs, as puddin' says early IOR and all that goes with that. To my eye, though, the 25 looks like they lopped off the molds of the 29 just to create a 25 footer. The tumblehome will give you a little more volume below, perhaps, but given the narrow ends and the truncated stern I'm guessing the Catalina will be a more liveable layout, and undoubtedly a better cockpit.
All else being equal, given the line's popularity and reputation for support I'd lean towards the Catalina - although an inboard engine would be my preference too....
