I was in the market for a new truck in 2007. I bought a Dodge Ram 1500 quad cab. I owned it for two years, and had no complaints aside from the gas mileage. At the time, it was the best deal (Lonestar & Hemi). The ride was a bit stiff, but was fun from light to light (very quick). The interior was mediocre, and the cabin can be noisy at highway speeds. I've always thought these were great looking trucks.
I also looked at the Ford, and would have bought it if it was as cheap as the Dodge. The cabin was much quieter, and the interior was better designed. The ride was more comfortable, but it seemed to have less power than the Dodge. I find these to be nice looking trucks, and the good looking interior makes for a nice all-around package.
I've driven a new Tundra, but it was much too expensive for me to consider when we were looking. The interior seems higher quality than the Ford, though not better designed to me. The Ford seems to be a little quieter as well. I found the ride very comfortable, and the engine has a lot of power. It felt more powerful than the Ford, though less than the Dodge. The styling didn't do a whole lot for me, so I was not sad it was out of my price range.
I wasn't overly impressed with the Titan. I liked the exterior styling (though less than Ford or Dodge), and the interior was mediocre (comparable to the Dodge, and less than Toyota/Ford). The engine sounded more responsive than it was (nice exhaust note), and I can't remember the ride quality. It had some neat gadgets at the time, though I belive the other manufacturers have caught up by now. The pricing wasn't good enough for me to consider at the time (more expensive than Ford/Dodge in 07).
I didn't test drive a Chevy. There were few discounts when I was looking in 2007. The new styling has grown on me, but I remember not caring for it as much in 07.
I have some reservations about buying a Dodge/GM product right now, which have nothing to do with the quality of their vehicles.
