first disclaimer - test was done, but glass in negative carriers and glass on scanner are full of dust, so final print is far away from usual cleanness. Also focomat negative is not 100% - I must peal negative mask to show 110% percent of negative to be able to get black border around picture.
But test is good enough to see difference: el nikkor has much more contrast, also you can see that in el nikkor (75mm f4) there is a little less resolution in details. Focotar (40mm f2.8) is lower in contrast, more details.
Also what I noticed that focomat light is not very bright like magnifax, but I need to check later do I have original bulb in focomat.
