It's not so easy to say OOP AJ is a fold. There's much more to it than that.
In a full ring cash game, if I'm UTG, AJo is often a fold for me. But it's not just because it's an easily dominated hand. It's because I don't know if the person calling me is playing a better A, or some other speculative hand, or a pocket pair of who knows what. And with 8 people behind me, there's just too much shit out there.
But in 6max, AJo is fine for me in any position really. Same idea with KQ.
Suited or unsuited really doesn't make much difference pre-flop. It's just a nice little leverage piece if your suit hits the flop. But in truth it's going to add about 2% to equity of your hand.
Anyway, back on topic. Hand value doesn't exist in a box. It's always relative to your position and your opponents ranges. KT OOP against a pre-flop calling station is fine. Particularly if you know how to navigate post flop. KT from the SB against a nitty BB is also fine. You can often steal and have a fair hand with a pretty solid idea of your opponents range if called.
In addition, if I'm out of position pre-flop against a Loose-Passive player almost any 2 cards are good because I can raise pre-flop, bet the flop, and get folds fairly often.
So... in short... it all depends.
