hand held tuner for ford f-150

I'm looking to buy a hand held tuner for my 2007 Ford F-150. Wondering what everybody use's.I've heard good things with the Superchips Cortex, Diablo Predator and the Edge CT/CTS. The truck has a 5.4 and is a 4x4 with 35" tires and a 6" lift.

Bully Dog  GT tuner, they are really working well on the 5.4s
