They're definitely nice. My parents have a 2011 F150 FX4 with the Ecoboost engine. Its close, minus the shocks, fenders, wheels, 315's and a few other mods. Still has the same 4wd and electronic rear differential except the Raptor can engage it in 2wd.
The FX4 does great off road and pulled me out of the mud easy after I buried my truck to the bottom of the cab. And with the Ecoboost, its the fastest stock truck I have ever driven. The Raptor has a 6.2 which is also a beast, but a little thirstier.
