Really depends on the preflop action and the texture of the flop. For example:
.10/.25 nl cash game (full ring)
UTG+2 raises to 3bb, everybody folds to me on the button. I have A10o and I raise back to 9bb. SB and BB fold, UTG +1 and we go to the flop that comes out
Ks10s9h.
UTG+2 bets 2/3 the pot: I'm pretty much behind or facing a hand with strong drawing strength so I'll maybe try a reraise if I'm facing a LAG player or I'll just fold to a very TAG weak player.
If the flop had come J102 and UTG + 2 checks, I bet it strong and won't slowdown unless I suspect that he has a jack in his hand (semi-loose player or TAG playing JJ by the book).
The answer is always dependant on your reads, on the table you're at and on your position.
