your post is all over the place but i'll take a crack at it and someone else will correct me as needed.
flex is probably more important than profile. a softer board can be buttered more easily because it's easier to bend. a stiffer board gives you a more stable platform for taking on jumps. i believe a softer flex board is also better for jibs as well as they're generally not as aggressive.
however, a rocker-profile board is slightly easier to press because of its inherent shape. but a regular/flat profile board is better for jumps because it gives you more pop out of an ollie due to the leverage created. rockered boards also tend to wash out on landings and are generally seen as better for jibs due to its more mellow ride.
