I had a G3 17.5ft and liked it until my family grew. I now have a XPress 20ft. My parents have a Rhino 17.5 Side Console and my grandpa has a Rhino 17.5 Stick Steer.

The Rhino is a lot more sturdy than the G3 because of the wide bottom. The Xpress is more sturdy than all but I can't really compare a 20ft boat to a 17.5ft boat.

If I had to go to a smaller boat it would be a Rhino because they ride smoother because they are heavier.
