All depends on your perspective, I guess. How do you define "comic book Gwen" or "comic book" anyone, as in that regard MJ from Raimi's SM was a piss poor MJ in many ways as well.Well she's certainly not playing comic book Gwen that's for sure. Mary Jane is supposed to be this spunky, fun character on the surface with her own demons that she's not showing anyone. And she's probably one of the few characters that really gets Peter and why he does the things hes do. Sounds like Emma's Gwen to me. It's not a carbon copy of course but there is more MJ than Gwen in the character that she plays.
Also have to take into account that they borrow a lot from the Ultimate uni and mix and match, along with just creating a new character. I don't think she was more MJ than Gwen, really. MJ was never scientifically inclined to any degree, nor did she have a relationship with her father that made her weary of Spidey, etc. So really you could say either or depending on how you spin it.
MJ is supposed to be spunky, sure, but she's also supposed to be really 'out there' and no where near as behaved/reserved as Gwen is. That's part of her evolution as well.
