I usually don't like to slow play Aces. As others have said, there are situations where you should, but for the most part you should not play it slow. Think of slow-playing as a trick to use occasionally to keep your opponents off-balance. If you do it too much it won't be as effective.
My reasoning for not slow-playing is this: suited connectors are very dangerous to aces. hands like T9s or 76s are the kind of hands you DON'T want to play against, because they can make for a lot of big draws that could cost you your whole stack. You DO want to play against small pairs and hands like AK or AQ, because you are a dominating favourite against those hands. As it happens, AK and small pocket pairs are also much more likely to call a raise than small suited connectors. So raise! Your purpose here is to control what kind of hands you play against.
Of course, it depends on the table situation as well - if you don't think anyone will call your raise, you might be better off slowplaying. But not usually.
