I'm a happy Teraflex user, so I'd go TF. Lots of those kits running around out there.
Another good alternative fro a true suspension kit is the AEV 2.5". More expensive, but incl's Bilstein shocks and a few more goodies. I put one with front control arm drop backets on a club member's '10 last year and was really impressed with the performance.
