To be fair, they're both good trucks, but I've bought a Tundra, sold it, bought something else, went back to the Tundra, sold it, bought something else, and now my next truck will likely be another Tundra.
I see the ecoboost like the cummins. There are many fanboys that some how their truck is magic and can tow 15000lbs and still get 28mpg. The reality is my truck gets ~1mpg better than my Tundra did, my Tundra had 37" tires, my Raptor has 35" tires. The ford doesn't feel quite as large when driving but still has lots of room inside, not nearly as much as the Tundra, but adults can comfortably sit in the back seat.
