Hi. I almost always raise here. He wont put you on JJ, and will probably credit you for spades. Plus if he has spades, he might reraise you and you get your money in with him drawing dead.

If you call, several bad things can happen:
Card higher than J and you don't know where you are, although this shouldn't be too much of a concern, he's probably not gonna stack off if he makes a pair, but you're likely to get stacked if he makes trips.

Spade hits, and he slows down with his overpair. Obv this is of no good.

Finally, if a blank comes, and he does bet the turn with an overpair, and you raise, he's much more likely to give you credit for a big hand.

Like someone said though its v player dependant. If the guy's really loose preflop then calling might be better since in that case you hope he pairs the turn.
