For 4x5 I use a 150. Never compared it to an EL Nikkor. I'm sure I'd never be able to tell the difference between an EL Nikkor, Rodagon or Schneider Componon-S. Even if there was a difference my print sizes from 4x5 negatives are too small to show it. In 35mm I did once try to compare a 50mm EL Nikkor to my 50mm APO Rodagon since the enlargement factor is higher with small negatives. Again, saw no difference at all. Both razor sharp.
