This play depends on the current typical pf action, stack sizes, your table image, your position, your postflop skills and the style (and postflop skills) of the other players.

With a short to medium stack, you should probably make a bet that will create a pot size such that a shove on any flop would make sense.

With a very short stack, a shove is probably the correct thing to do pf.

With a very deep stack, an overbet will have to be a calculated choice based on the factors I mentioned in para 1.

In general, remember that you play poker to win money (or chips) so you want to get value for your good hands. If you go all-in with 200BBs, you will win 1.5BBs very often and may get called from time to time with AK, KK, or QQ. However, sometimes players will fold those hand to a 200BB all-in bet so you will be losing lots of value.

As well, large overbets might get hands like AT, AJ, AQ, KQ etc to fold where a flop with a high card in it might get lots of chips from those hands if they hit.

Edit: As a last thought, a normal raise may be more likely to get re-raised than an overbet. Again, this may give you more value.
