While I will appreciate having Pokemon Bank in general, I voted "For Poke Transfer with the subscription" because that's the more accurate situation. Mostly I just want access to Pokemon Bank in order to transfer my Pokemon over to Gen VI. I don't overly trust cloud services and likely won't store anything too important on Bank long-term, just random Pokemon that I'd rather not release entirely (ie. breeding stock with good eggmoves or IVs), extra legendaries, etc.
Most of all, I just want access to my team Pokemon from past generations. Being separated from my babies is cruel, unusual torture. </3 (We ignore the fact that I can boot up Black2/White2 to see them whenever I want :'D)
