I can't afford a 2013, so that's not a choice. I don't drive the truck much when not pulling the trailer, but do make sure it gets driven at least once a week. My choice is between an 05 to 07 5.9, or a 07 to 09 6.7.
Owning an '05, my complaint is with having only 4 gears. 6spds are hard to come by (or want a stupid amount of money for). My dad's '01 6spd Cummins (Edge-EZ) is almost better in the hills than mine, only because of the closer ratios.
Because of that alone, I would be tempted to go with a '07.5+ to get the 6spd auto.
When I purchased, I wasn't hard set on a 5.9L, but was about 90% sure I wanted a 3rd Gen body style, and really wanted a MegaCab for my growing family. My goal was finding a very clean well kept truck with the options I desired (4wd, 4 doors, not a work truck model).
I bought my '05 4yrs ago with 62k on it for $24500 (SS step bars, fiberglass tonneau cover, sprayed bed liner, BigHorn Package). I have 111k on it now without issue. Gets ~13mpg towing my 6k toyhauler. The back seat is a little cramped being the quad cab, but it works for us, and at least I was able to get a long bed, but I do still dream of a MegaCab from time to time.
If I would have found my truck, for my price, and it had a 6.7L, I would have bought it. I would have lost some fuel economy, but gained towing ability, which is what I use mine for the most anyway.
