Replying to K2 Fujas or obsethed or s3 ?

Hey guys, I go in Utah for 1 week in february and i need a ski that can rip powder, groomers and park. I never skied in deep powder ( im from Quebec) . So which one will be better for powder, groomers and park? Btw im 5'10 and 150 lbs and i ski 176cm dumont if that help. I will mount some marker schizo on the ski. I know the obsethed will be better in pow, but how much better than the fujas or the s3? I don't buy the ski just for one trip, plannig to go to whistler next year. Planning to buy the ski next week . +karma for help.
