There are artist´s that i see more as Spider-Man artist´s that other ones,even so i am of the opinion that many artist did great art in Spider-Man stories the last decade.
I mentioned some but i could add the art of Olivier Coipel and Jim Cheung,also incredible artist´s that painted great Spider-Man stories.
Thus why it´s quite dificult to say who was the best Spider-Man artist of the last decade to me.
