The Future Foundation Spider-Man is the best looking variant out of the two options available. I like the Big Time Spider-Man Green Suit on paper, but as a figure it kind of is disappointing. I've also seen bad reviews of the figure on youtube.
I am hoping that next year we get a Humberto Ramos Spider-Man figure. I've become a huge fan of his art since he took over on Big Time. He deserves a figure depicting his art.
