Are Adrian Peterson and Brandon Jacobs a better fantasy group than Steven Jackson and LaDanian Tomlinson?

Peterson's the #1 back and Jacobs should get several touchdowns. Jackson and Tomlinson are both on the back end of their careers but both have a lot to prove this year. There's no one really backing Jackson up but Tomlinson has a spell back in Sproles. Peterson and Jacobs have solid backups also although Peterson does get the majority of carries. I'd say Peterson and Jacobs is the better group since they are going to get a lot of yards and touchdowns compared to Jackson and LT.
