I own a 2500 Chevy crew cab but looked at the 1500 crew's when I was shopping. I didn't get it because I wanted the diesel with the Allison tranny, which was only available in the 2500HD (plus they gave me a deal I couldn't refuse). However, I still feel that the Chevy 1500 crew's offer quite a lot more than the Ford or Dodge half-ton crew's. First, Chevy makes theirs a 1500HD, which means almost everything on the truck is the same as my 2500 except for the engine (stock is the 6.0L Vortec V-8) and the tranny (the 4L85E). With the Chevy crew you get things like a heavier frame, 8-lug wheels, etc. than you do with either the Ford F150 Supercrew or the Dodge
1500 Crewcab.
The Nissan certainly looks like a nice truck, but there are certain little things that have turned me away from both them and Toyota. For example, I looked under the rear end of the Armada, the SUV version of the Nissan Titan, and the rear differential was so small in comparison to my truck that it looked more suitable for use in a compact pick-up than in a supposedly full-size truck. Plus the traditional Big Three give you a much broader range of choices in trucks than any of the others we used to call "imports".
Just my two cents worth.
