If we take into account which was performed first in history, that would suggest that 3Lutz is easier the 3flip for both men and women, but I don't think anyone is making that argument. Or that loop was easier than toe loop even though Button did it first.
Are you also looking at how many men in the 1980s, or 1970s, could do 3loop vs. 3flip?
Just out of historical curiosity, it might be interesting to make a list of as many 1980s women as we can think of who could do harder triples (loop, flip, lutz, and axel) and who could do which. Maybe I'll start a thread for that purpose.
