I figured I'd offer my input on this. (After I finally figured out my user/password combination to my account I haven't logged onto in 5 years I see).
I've been a lifetime GM fanatic, which I learned from my dad. I currently have 6 GM vehicles, 2 Fords, and 1 Dodge (mostly classics), so I've definitely had a bias. I'm finally in the point of my life to where I can afford the new car I want, so I've decided on a fullsize truck. I tried very hard to like the new Silverados, and I've looked forward to the day where I could buy one for my whole life. I tried real hard. My initial impressions were that I hated the brick styling with the flat hood. There was too much chrome in the slab front end. And there were no model differentiations that I could see on the lot. Just looking around, there were the base W/T's with black grills, most trucks with standard chrome grills, and the super pricey Z71. I couldn't tell them apart, inside either. They tried to show me their "Rally" package I think it was, I had to keep my lunch down from that, talk about a mess. Then I went to check out the Rams. I saw a slick looking Sport that got my attention, super clean, sport truck look. Then I saw the Tradesman Express, same color keyed bumpers/grille, but slightly cheaper interior. Then I saw the Big Horn with just the right amount of chrome, and a nice interior, and many great standard features. But the Laramie was fairly reasonable as well. And all 4 of these had totally different looks, I can tell what one is from a 1/4 mile away. GM is dropping the ball entirely in my opinion. The GM is a great truck mechanically, but they can't sell me on that alone.
Which is why when I sell my restomod Mustang, I'll be buying a new Ram in about a month. Throughout this process my dad has gone with me to look at trucks. We drove both Ram and Chevy, and although he has bought ONLY GM trucks his whole life, he bought his first Ram last weekend. A Big Horn crew cab, and he absolutely loves it, couldn't be happier. For our purposes, both trucks tow what we need. I know GM's reliability over the years has been good, but Ram has been much improved, and a lifetime complete mechanical/electrical warranty can be had for cheap. Aside from that, Chevy said they would knock a whopping $2k off their MSRP, meanwhile my dad's Big Horn was had for $12k off, a $41k truck for $29k. And this truck had many features we liked that the Chevy we drove didn't, such as electric locking tailgate, electric sliding rear window, under rear seat storage + package tray (Chevy tried to talk up the additional cost accessory that accomplished the same), better looking (20") wheels, buckets/console, rear seat A/C vents (HUGE deal), rear floor ice chests (cool gimmick), 8 speed (huge plus), chrome (not black) ext. door handles, able to add trailer brake with plug in switch (Chevy said not doable/not prewired), just to name a few. But they were mighty proud of the bumper step (which I think is ugly), and the triple weatherstrips on the doors. Plus the Ram just looks beautiful IMO. There's not an awkward line, it flows, isn't too in your face, and has nice wheelwells (I used to be okay with the square wheelwells, now they have gotten comically square, looks hideous with any custom wheel/tire application).
I really hate to sound like I'm bashing the GM trucks, but I just wanted to let this out why 2 people who have been GM DIEHARDS their entire life are going with Ram. I'm just airing this out in the hopes that someone from GM will read this, and understand. Not going to change my patterns right now, but hopefully I might be swayed in the future.
