I've owned the 330 Express, then a Marlin and now a 330 again. For me it is worth it, but I use my boat as a home away from home and overnight with wife more than I fish. When I decided to go up to the 330 again, my wife stated "why, we can do everything on the Marlin that we used to do on the Expresss." which was true. But for creature comforts the 330's extra space is nice. It is also more comfortable with more people onboard due to the center helm and seating and it rides a little nicer. Fishability is actually a little better on a walkaround. Performance numbers are nearly identical. So, like what was stated, it depends on your desires.
