How strong are your AA?
Obviously there's a huge difference between A

and A

If you have crappy Aces, limping along and hoping to overset someone is probably the way to go. Your hand is nicely disguised when you do hit and you're often taking a stack off QQxx on a AQ3 flop.
If you have stronger Aces, then raising for value and playing poker post-flop is the way to go, especially if we're in the SB and raising gets the BB to go away (if he sticks around we're in a ton of tricky spots post-flop trying to get value OOP multiway).
