Quad VS Thruster

I'm considering swapping my thrusters for a quad setup on my 7'6" Submoon Firewire. (First a disclaimer: No I'm probably not a good enough surfer to really tell the difference.) If my fins were in backwards I could probably tell though! All the same I'm curious about what the rest of you think of Quads? I know it'll be faster. I rode a Haydenshapes Plunder with quads once and It basically kept squirting out from underneath my feet. I guess it was too fast than I was prepared to ride it? But when I'm riding sloppy beach break I'm thinking a quad setup might help me to get around close out sections and just have a fraction of a longer ride.
