Thanks! It's very close! His eyes look slightly clearer/sharper in V11. The aliasing moves around but doesn't seem like one is better than the other. The rings on his neck look more correct in V12.

Take your pick! :-) I would probably go with V11 if I had to pick one because it was such an amazing jump in quality when it was first presented and it is scary to mess with it further, but V12 is nearly the same and has things that are better sometimes. I don't recall it having more detail than V11 while there are several times when V11 has more detail than V12. V12 is better at antialiasing at times making it look better than V11 in those spots. It might be easier to see differences with aliasing while it is in motion and that might make V12 better, but hard to say.

That's my .02. Happy with whatever you decide!
