QQ81.4690.40218.12981.670
JTs18.1290.40281.46918.330

We compare a pocket pair with a suited hand. A pair against two lower cards is a lopsided matchup: the pair is ahead and the other hand has no overcard to catch.

That is a heavy lead: JTs needs the board to help it on most runouts and still falls behind far more often than not. The tie share is 0.40%: on those boards the pot is chopped and neither hand wins outright.

In the ranking of all 169 starting hands, QQ is number 3 and JTs is number 45.
