KQ is setting you up to lose a big pot with a weak kicker...assuming you think your hand is good when it hits.
The agro player will likely back off of a board with kings and queens on it if he didn't hit..KQ looks a lot like big pairs in early position. win small pot or lose big pot...KQ is more likely to be a hand an agro player is wanting to play against...

9 10 suited is way more versatile...easy fold if you miss...nines and tens on the board= c-bet for an agro
better chance at winning a big pot with 9 10

I like 910 against an agro showing up with KQ seems like showing up to a gun fight with a rubber chicken...at least 910 suited is a knife and gives you a chance.
