well thats a pity. I'm not asking which is best because there is no such thing. I am asking what is the difference on only graded papers between the two developers. I would be more than happy to know one is better for highlight separation and one is better for shadow separation because that would give me two different tools for two different requirements. But if they are both very similar then I will only test one (for now).
So far I've a couple people say there's no real difference in the print and one person say there is a major difference. That leaves me having to test both developers.
