I spent most of the early season last year at Bear and the late season at Big Boulder. I really like Bear's park but by March it was basically unskiable. It slowed down so much that you couldn't even reach the top of the lip on their big jump and barely had enough speed to clear the other jumps much less attempt tricks.
I think all of the parks have their pros and cons but you really just have to be on top of the conditions. There's nothing worse than driving all the way to a mountain only to see that the conditions suck and you can't really do anything.
