I switched to an F150 and have no regrets except I miss the triple cup holder! The 5L feels nicer, sounds awesome w/o being overly loud, easily out runs my old 5.3L and it's holding up fine. The interior is notably better impo and it lacks the rattles and squeaks I'd grown used to in my Silverado, which is still in the family, btw.
I've no interest in the 3.5L ecoboost either, but the 2.7L is interesting. Everything I have read or heard about it suggests it gets all of its rated fuel economy and makes more power and torque than rated. I prefer V8's in general. I would have bought another Silverado, but I only wanted a crew cab and I did not want to buy 1 built in Mexico. I actually like the Ram 1500, particularly the diesel. However, I did not like that dial shifter. Besides, it reminded me of molasses each time I hit the throttle.
CONGRATULATIONS! I think you'd be happy with any, as long as you initially decided it was worth buying. They all hold up these days and it's really just a matter of personal choice.
