This thread hits right to home. I own a 2014 GMC Sierra and my Dad just bought a 2014 Ram Laramie.
There are things I like about his truck, and there are things I like about my truck.
I like how light the doors are on my Dad's Ram, but it doesn't feel cheap. Still closes with a solid thud. The doors on my Sierra are so ******* heavy!
The Ram leather seats, while don't get me wrong, is nicely appointed and comfortable. I think the leather is nicer in my Sierra and the seats are more comfortable.
The Ram's heated steering wheel heats more evenly. My Sierra has hot spots, mostly near the bottom of the steering wheel. But my heated seats get hotter and have a larger heated area on the bottom cushion compared to the Ram.
Ram crew cab vs Sierra Double cab, not a fair comparison. But at least the Ram has rear vents on the back side of the console....not even the Sierra Crew cabs get those.
The Ram 4 corner coil suspension is great! Leaf spring suspension can feel "loose" from the lack of sway bars. The Ram feels tight around corners, even on a Crew cab, 6'4" bed that my dad has!
HEMI. Enough said. even with the 3.21 rear end ratio, the Hemi would blow the doors off my 5.3L. Also the ZF 8 speed in the Ram is superior to the 6 speed hydramatic GM transmission. I have the 3.42 rear end in my Sierra.
Anti-Slip Rear axle in the Ram is awesome. I've never driven a limited slip equipped truck before. I've only had the GM' autolocking differential and ford electronic auto "locking" rear diff. The LSD in my dads Ram is absolutely outstanding.
I like the exterior styling of the Sierra over the Ram. But both are still attractive trucks.
The fuel mileage in my Sierra is better than the Ram.
The Ram's infotainment/navigation is nicer. But the system in my Sierra isn't that bad either.
The driver info center on the Ram is awesome. way more customizable compared to my Sierra. But I like the analog gauges in my Sierra compared to the analog gauges on the Ram. The needles on the Ram are too fat.
I have easy lowering lift gate standard on my Sierra. Ram does not. Gonna have to get the piston thingy for my Dad.
The hand controls and pedals are a little awkward for me to use on the Ram. I am more comfortable with the positioning in the Sierra. But I think I could get used to the Ram's if I drove it everyday.
I could go on for days and days.
I like both trucks. Both have their strong points. We also drove Fords, I even owned one for a short stint. The Ram's and Sierra/Silverados are definitely top notch.
