first off, fat skis are skiable anywhere...as long as you are a good skier, you can make anything turn. I live in VT and use Seth Pistols as my everyday/everywhere ski. Enough of this "fat skis should only be used in the powder" bullshit. Snowboarders ride there "fat boards" everywhere, no matter where they live.
But to answer your question, I can't answer it. It all depends on what you want in a ski. The only thing I can say is demo them both if you get the chance.
