I wanted to buy a newer GM in the worst way recently because that's what I historically buy for trucks. I went to a large used car dealer we have in the area which has a lot of 1-3 year old off-lease vehicles of all makes, figured I should see what's out there and what's new. Spent pretty much all day looking at different makes in and out, laying underneath, looking with a fine-toothed comb. I do a lot of mechanical work and body work for years, built a few street rods too, so I like to think I have a pretty good eye for the good and bad. Like others, I too felt the interiors of the GM's were lacking in quality of materials and layout (IMO), the more I looked at the styling, the more I didn't like the squared-off fenders look or the two flat boobs on the GM hood. Fords had nicer interiors by just a tick. But the Ram's interior seemed laid out nicer. I personally don't care for any of the cloth they use on any trucks these days. Just seems cheaper than what it used to use. Leather doesn't do me any good. I'd rather have an old-school 60/40 bench too, not the 40/20/40 arrangement, but those have gone away too.
Ram has nice attention to details like plastic rear box inner fender liners to help reduce rust (the GM's that were just a couple yrs old were already really rusty around the wheel wells). The frames on the Rams were cleaner where the GM's were already getting rusty! When you have a vehicle that within a couple years is becoming rusty, that's an issue to me.
Hood visibility out of the Fords and GM's was abysmal IMO and the Ram is better. I didn't care for the really tall bull-nose look of the Fords or GM's. The hoods used to be a lot lower and visibility used to be a lot better!! These companies are going the wrong direction. The GM door handles are down low, didn't care for that. The Ram box seems to be a like 2" wider due to narrower wheel wells. Ram has a pretty nice sound system, even the base system is pretty good. On the regular cab rams, there like 12-13" of space behind the seat to put tools and stuff. For a lot of guys (including me) that's enough, so I don't need to go up to a longer cab and more cargo (8' box), which is nice!
The truck I ended up settling on is a high mileage 2012 Reg cab 4x4 which I got for a sweet deal. I was actually looking to get something newer and less miles, but the doors have no play at all, it drives as tight or tighter than lower mileage trucks I drove that day ....and no rust starting unlike some of the newer GM and Fords (Ram must use a little better rust strategy??). That says something to me. Plus the 5.7 Hemi allows for heavy trailering when the time arises. I prefer the styling of the Ram over the others. Having owned a few Jeeps over the years, they've been great vehicles for us.
In the couple months of ownership I haven't questioned buying it one bit. Some of the maintenance things are well laid out (easy access to filters and drain plug). It's a treat to drive. Not one squeak, rattle, hiss or burp, and it's got over 100k mi. Looks nice, I don't abuse it. At the same time, if some prepubescent diesel dude thinks his Ebay-chipped so called "torque monster" is going to pull a fast one on me, it ain't going to happen, not in THIS truck! This thing will rare back on it's haunches and charge like crazy if you let it. I'm getting about 17.5 mpg (averaged) with it driving it gingerly, which is a little less than I was expecting.
Anyway, hope it helps. Good luck!
