#2 is better. But both could be fine tuned. You have low attack values, which could be helped by GF Thor, perplex, GF Cap, and the avengers initiative TA also helps hitting. GF Hawkeye is really great because can hide behinds allies and shoot. GF Hulk is a must, he is simply outstanding, you might wanna top him off with Infinity Gauntlet and Soul Gem.
Btw, forget about the starter Avengers figures, they are lousy.
