We pretty much have the nuts here as neither of these Villain would 3 bet with Ax.

So the question is do you raise the turn, or wait to raise the river?

Against average player raise the turn as he is unlikely to fold a weaker hand. Especially since he knows that an A is already gone, this will give him more reasons to call.

Against a good thinking player wait til the river as he may fold KK or worse on the turn. This is even more true if he perceives you as weak tight (due to all the missed flops that you had to fold), or unsophisticated.

If your table image was different (say more aggressive and tricky), I might prefer raising the turn vs a good player as he might think you are trying to push him off a high pair, given that an A is already gone.
