tbh, I can't see anything that P1 is superior to this one, except in the price, the base and perhaps the more marked grin in her lips makes her more sensual? iconic? representative of the character?
The price doesn't matter anymore, because these statues never competed in time. If you are lucky enough to find a P1 at a retailer today, it will cost you more than JND (maybe not including taxes).
The base is empirically better in P1, but I also have some problems with it. It's too tall for a 1:3 scale figure (since I want to display it in a high place), the Hello There neon is already too redundant for me (since I have one of those from etsy) and that loose cat over there can generate this type of "catccidents" xD

And the face matter, well, that depends on taste, but it is undeniable that MP is in both figures.
In the rest of the matters, I see JND superior or very superior to P1.
