Exclusive Box sets, or Individual packaged toys? (Your Preference?)

So, fellow collectors. Which do you prefer when collecting bots from a toyline? Usually, I'm all about box/gift sets when it comes to gestaults and nothing else. But for some reason, the exclusive box sets (1st Encounter, Desert Attack, Sam's club, etc.) appealed to me in the movie toyline. I keep the exclusive box sets MISB, while opening up doubles I buy that are individually packaged.
What about you guys? What is your take on these boxes? Or your general preference? Do you love/hate em? Do you like to open those instead of the normal packaged ones or keep them MISB?
My main beef with them is that almost always they're already in robot mode. I like to work my way from alt mode, to robot mode as the end result feels more rewarding.
