Which hand would you prefer?

[spoohunter]

While dual tabling a few mid limit stars games I observed a hand, which, on the river, with the same card, made both the straight and the flush. The straight for QJo and the flush for 42s. Now, I naturally guffawed (as I usually do when I see an inferior hand beat a superior hand) when it dawned upon me that QJo was playing from UTG+1 and 42s was playing from the button.

So, which would you prefer? QJo from UTG+1, or 42s from the button?
