For me, it's more about having a wider range of available characters to use.  Even with all of the distinct characters we have on the market for the Daz series (all of them) you can tell what they are...Daz products.  Michael, Genesis, Victoria.  I want differences, major ones.  As people are in real life.  Variety.  Even if it is just for my art and my learning process, for me it's not a waste of time.

and yes- LOATHE the Rex eyelash thing. I mean, really? O.o
