Very familiar with Tundras, a bunch in the family.
Pros and cons like everything else. The 5.7 is a beast of an engine, in the same league as the GM 6.2 and Ford HO 3.5 EB, especially with the 4.10 rear. The cabins are a let down. The 1794 leather is quite nice, but there's just acres of hard silver and black plastic. The driving feel is also much different, probably the most critical difference. I don't think the steering is as precise as a domestic truck (especially GM), the brakes are super touchy, and there's just more NVH. A GM truck is going to drive and handle a lot better, and IMO be less fatiguing to drive on long trips.
As for the 3.0, I'd skip it. To me, light duty diesels don't make a whole lot of sense. The US isn't a country where diesel has a massive tax advantage or an engine displacement tax. Yes, they're a bit of a novelty and put out good MPG numbers, but servicing is a lot more expensive. So you probably break even in the long run cost wise, but get a much slower truck.
