Ultimately, build an army that you want to play. Based on the rumors of fifth edition (which is rumored for release in 2008), rhinos may again be seen en-masse since it's rumored that only Troops for the force org chart will be scoring units (I have doubts about this, but it is the current rumor).
I wouldn't count on only troops being scoring units, but
GW has made really bad calls in the past. Regardless, Dietrich has it right when he says that you should build an army that you want to play. In the end, it really is about having fun. If you have to crush your opponent's soul and see them cry as they sweep their dead models off the board turn after turn in order to have fun, then this isn't the army for you. If you want to play a bunch of marines in transports with heavy tank backup and you don't care too much about your win/loss record, then this is what you're looking for.
