I'm a long time member of both Ford-Trucks.com as well as Powerstroke.org. To even mention those posts as being some type of problem would be like me saying that buying a RAM will absolutely result in your front frame section coming apart (per the new recall). The chances of your truck experiencing the "jack hammering" issue a few have mentioned is almost none existance. The few people that have experienced the problem tend to voice it the loudest because they are expecting a fix (rightly so or not). The fact is that out of the possibly millions of 6.7s on the market, less than .00001% have every had that type of issue.
I'm on my second 2011+ Supert Duty (2011 and now a 2016). Both trucks performed flawlessly. 2 month ago, when I purchased my F450, I look at trucks from both RAM as well as GM. Though their trucks are nice also, I found that only Ford offered some features and ergonomics that fit me. Ford seats put RAM and GM to shame for long distance comfort. RAM Seats are like sitting on a finely leather wrapped piece of plywood good for about 1 hour of driving. I LOVE Fords Power Fold and Extending Tow mirrors. I LOVE the Manstep (which is probably the single best invention for a pickup truck ever). I LOVE the power of the Power Stroke 6.7 and the power curve it offers (doesn't feel sluggish like the RAM and GM did). If you dissagree with that statement, then you obviously haven't driven all 3 trucks, like i have, to compare.
The stability of the front wide track axle and the over-kill capacity of the Dana S130 rear Axle also make the truck one heck of a towing beast.
All 3 trucks are nice. I personally believe that Ford has the most experience as well as refinement for a HD truck to date. Even if you look at the interiors of all three, one could easily argue that RAM has the most refined and best looking interior, but the cheapness of the materials brings to question the longivity of them. Ford interiors are known to hold up extremely well over time (something RAM and GM can not even come close to bragging about). The reality behind RAMs "soft touch" interior is that it's really only on the door panels.
