It's close, but not really because of the pot sweetening effect many think. With a premium hand you have to raise, becuase your edge is significant. But your preflop equity with a hand like this isn't THAT big. You don't even necessarily have the best hand (a lot of weak tight guys will limp with AQ or AJ after 2 or more limpers), they'll be a pair out there already, and you probably have a couple counterfited cards. You're out of position the rest of the hand. And you have no post-flop fold equity. You have to play near-flawlessly post-flop to be able to take advantage of your preflop equity share.

In position after a limper or two, your raise sets you up to take down the pot unimproved. With AJo, you migth raise a guy with pocket 6s or A5, but you still take the pot down on a K Q 5 board with the worst hand.

So if you can play masterfully post flop, push that edge. Otherwise, just completing can make the hand easier to play the rest of the way and take advantage of some post-flop mistakes.
