Final opinion for lift and wheel size

I have a 2011 Silverado 4wd. I am looking to ditch my leveling kit and go higher in the near future and have read many forums on here about different lifts, wheels, tires, mods, etc. This one was especially helpful for those also looking into lifting their truck also: http://www.gmfullsize.com/forum/showthread.php?t=285328

That being said, I am torn on what lift to get. I am down to these 3, but can't decide and want one last opinion before I pull the trigger: 6" Fabtech, 7-9 FTS, or 7-9 McGaughy's. I'm looking for final REASONS to go with one over the other. After that the search for wheels and tires begins. I want 35s on either a 20x10 or 20x9 wheel. Looking for REASONS to go with either wheel size and what offset would be needed would be appreciated as well.

EDIT: I'm looking for a semi-aggresive look stance wise. I want to be able to cover my tires with fender flares in the future so I don't ding up my doors as bad.
