Well, here's my two cents, for what it's worth (about two cents):
Yes, the pros do use Autotune. Some of them, some of the time, anyway.

Just wondering how useful Autotune is if you've got a good singer. Is it really that transparent?
So far as I can tell, it's pretty transparent, if its not wantonly overdone. "Transparent" meaning a listener who only hears the "autotuned" version can't tell whether or not it's on there (though he might well be able to tell the autotuned version apart from a non-autotuned version, if he heard them side-by-side).
Whether the performance might have been just as good, or better (more character, less perfection) without it is another question, which depends heavily on the singer.
Whether the performance might have been better without the Autotune, but with a better singer, is yet another question. But it's not an enormoulsy pertinent question in day to day life if you're not the person picking the singer.
It seems like it might help the track "punch" through the mix better.
I don't know about that. "Punch" would seem to be unaffected, unless you mean that with Autotune you can bear to turn up the vocal loud enough to hear it without cringing. Besides that, I suppose Autotune, if anything, diminishes the "punch" in a sense: obviously wildly off-pitch vocals
do have tendency to draw attention to themselves.
Is this an essential in the studio?
A real "pro" could answer better. I guess it's essential if you want to make a not-that-good singer sound highly polished and radio friendly. Which is more-or-less what a lot of professional studios are hired to do.
