One thing you may want to consider is the firmness of the floor if you're going to have folks standing and fishing. PVC tends to be a stiffer material that you can inflate to higher pressures, so it'll make for a better casting platform. My Vanguard's floor is firm enough you could tapdance on it.
Maravia's drop stitch floors are pretty firm also, Hysides tend to be fairly squishy.
Good luck shopping!
