I would be sort of reserved in regard to this kind of comparison. There is a 
number of factors besides primary mirror itself influencing final 
performance. The seeing changes constantly, and it may favor one over the 
other at any time. Distribution of the warm bodies (observers) for the two 
may not be identical. Diagonal flat is not the same. Structural quality and 
properties are not identical, even if built by one same person in the same 
manner. It takes just a small difference in the degree of miscollimation for 
noticeable effect on subtle details. The spot one's standing on may be a bit 
less comfortable for one scope, causing slightly more of physical - and 
eye - strain, and so on. Some of these factors can be written off after 
repeated numerous comparisons, but some of them will always be suspects. It 
would take me very long time (read: forever) to decide one mirror is better 
than the other one based on small at-the-eyepiece performance differences.

That adds one more item to my "wish list"...
