Jake is more of the darker side, he plays more depressing roles, like the boy you like who's always quiet and when you finally talk to him you realize all of your similarities in dark thoughts.
Tobey is more of the lighter side. He's like the quiet "geek" that you secretly find adorable. Basically the boy next door, that you've been living next to for the past 15 years and you don't notice him until a special moment happens.
Those are my thoughts on the two of them. What are yours?
