Burton Process, K2 darkstar, Ride Agenda?

i am 5"11' 150lbs intermediate looking for a snowboard. after a lot of research, these three snowboards are left for me to chose from. They all have what i want, but i am not sure which. What do you think and why? i guess the biggest thing i am looking for is which is better quality and will last me the longest and just which is better in general?
