Well, smaller studios usually don't have the resources or manpower to create big games, so they have to innovate and break the mold. On the other hand, AAA developers can create gigantic games with tons of support, but they are limited by the fear of failing and losing a ton of money, so they usually stick to formulas, safer but less original.
Smaller but more original games VS safer and bigger games. It's a matter of opinion.
