Depends on you.  If you like fast pass kings Dominion.  I'd stay away from Busch gardens.  It's beautiful and the coaster's are great, but everything else is a nightmare.  Hershey has some really unique rides and diversity though.  A giga wing coaster, a vertical 97 degree drop coaster, an Lim launch coaster that's awesome, a wooden racer, an inverted clone, a boring looper, a wild mouse.  Eh, Hershey really has some unique rides though, I still say kings Dominion.
