Replying to Thoughts on Trampolines?

Ok so right to the point, is it worth it to practice tricks on trampolines? In my opinion it is, however a lit of people have been saying no its not the same and it practices bad habits. I do know that many tricks are different on a trampoline as you don't have skis. Also what are your thoughts on tramp parks? What similarities are there between trampolines and snow? Differences?
