The comparison chart of older fast 50-58mm primes and a pdf on individual lenses is available below. On the comparison chart, the lower the number, the better the lens!
There are some translations on the following forum discussions, which I copy and paste some below. The magazine chart ranks the lenses on more than just the sharpness numbers.

you see konica hexar scores 166 wide open compared to pentax 101 , based on this test at f1.2. hexar is actually the worse.
The following comments are from various people on:

It doesn't look like the AL version of the Canon lens scored any better than the standard S.S.C. It happens to be about 20 times as expensive though.
Hmm . . I just bought a Nikkor 50/1.2 AIS (NOT a Noct BTW) and it appears that it does quite well in these German tests compared to some of the other lenses in it's class. I think the Bokeh is probably not as good though.
That test actually said pentax F1.2 is sharpest wide open lense. (or best 50mm f1.2).
test does not include canon 50mm f1.2 (L version). My impression is canon version being almost equal or slightly better than pentax version in terms of sharpness. (i might be wrong though).
What the heck????!!!!! Last time I've seen a Hexar version of the 57mm F1.2 it cost twice as much as the Hexanon AR version which is the one we've been talking about here. To find out it's such a poor performer it's a shock for me! It's been a long time and memory might fail me, but perhaps it was a limited edition for the Hexar RF, I have no other explanation...
Anyway acording to the Konica Bibble:
http://www.buhla.de/Foto/Konica/eHexanonHaupt.html
Hexar lenses were subcontracted (probably to Tamron) and they didn't stand up to Hexanon quality
So to sum it up:
Hexar AR = decent performers.
Hexanon AR = outstanding quality.
