Without any real first hand experience, I would guess the scorpio would paddle best under a load. It seems to have more volume.
I have paddled an Aquanaut loaded and it did fine. It too should do well with a load.
Any boat with a load is going to paddle slower, have significantly more stability, and be slower to maneuver while sitting lower in the water with a longer water line.
