Well, I can't claim to being a PoP fan at all, since I didn't watch the show or collect the toys. (I had 'outgrown' toys by then.)
Basically, I have no frame of reference to PoP or NA at all.
Still, when it comes to figures I'm not familiar with, I tend to judge the figure purely on the basis of the sculpt. If it looks cool, I'll buy it. I don't want to be closed-minded and buy only things familiar to me.
So for that reason I have She-Ra and Optikk arriving this week from a 3rd party, and I'm looking forward to having them in my collection.
They definitely belong in the line from a sculpting point of view, and I'm looking forward to reading the bios.
