Here's a different way of thinking. Something like 87suited might be the hand most likely to win when you get to showdown, but that question is actually irrelevant. The question is which hand will lose you the least money to AA.
Level 1 answer: 87 suited if we're going all in pre-flop
Level 2 answer: It would be something like 44 -
hands where you have a strong chance of extracting max value from AA if you do flop very well. (E.g. AA not going to stack off on a board of J109 and a flush-draw too often, but it will stack off on a board of J74 rainbow)
Level 3 answer: 72 off suit - because you fold it preflop safely and so avoid playing AA, where you always expect to lose more than 1bb/hand
And the real answer from my database of over a million hands of cash games played? Of hands where I voluntarily put chips in the pot and villain had AA, 64suited lost me the least money. KK lost me the most.
