I don't know what an Imatest unit is other than a higher number is better. There is less than a 10% difference in the measured center frame values for these lenses.

How much of a measured difference is discernible versus "significantly different", which has to do with repeatability of the measurements of the two lenses? If you measure the same lens 10 times will you record the same Imatest values or is there variability?
