The problem with QTo is when it does win it usually beats only bad hands, and you're not confident of winning, so you don't get much money. T9s is more likely to win with a straight or a flush, where you might beat two pair or three of a kind; and where you could make a lot of money.

Another advantage of T9s is you will fold it on the flop unless you get a four flush, open-ended straight draw, a set or two pair. You have to stick around to the river most of the time to see if QTo wins.

I'm not saying T9s is a great hand to play, or that you never call with QTo; but suited connectors have more promise than unsuited one-gappers.
