Finally called Transgo, talked to Jim.
He said that the babbitt is normally used for softer torque converters (?) and that bronze is fine for the factory converter. Dimples help keep it cooler and have no ill effects.
So, dimpled bronze it is! I didn't know they made torque converters out of metals other than steel.

Upon further research, I find that my new bushing is made of an exotic material called "Babbit" of which I have never heard.
Any thoughts on this material? From reading online, it sounds like Babbit doesn't last as long, but people prefer it over bronze somehow. And then there's the issue of the play in the bearing. But that may go away when the bearing is jammed into the pump seat.
I'm going to wait until my new tool gets here and install the Babbit bearing to see if the play goes away. Very interested to explore this new space material.

In a perfect world the bearing never touches the shaft, that's what lube is for
that said many quality converter re-builders use hardened converter snouts
BIG issue is the clearance- one bearing is tighter than the other and you do NOT want a hemorrhage here
some even use a different bearing from a different trans to tighten up the clearance (I forget but you may have to grind the snout undersized to do that trick- Jim would know)
you can always check your snout for run-out, a wobbly snout will ruin any beariong
