Is weight a big issue for you ? The Phantom is a lot lighter than the SuperStocker. It's also a lot more versatile with interchangable barrels and breeches. If it's your first pump, I'd suggest the Phantom to start. Less initial investment and more versatilitiy for what you pay for. I personally don't have a SuperStocker, but if it's anything like PPS other guns then it's exceptional quality. Don't get me wrong, the SuperStocker would be an awesome pump gun, but I think the Phantom would be more friendly to someone just starting pump.
