Other Choices:

In the field of full-size trucks, brand loyalty is an especially strong factor, with die-hards for the bow tie or the blue oval. But objectively, next to the F-150, the Silverado offers better steering and sharper handling, though some might like the F-150's interior design, which is more businesslike yet still upscale. Styling is a big differentiator; the Sierra has a softer design, while the other competitors have the more aggressive, faux-semi look in front. Fuel economy is a strong point for the Sierra; with the 4.8- or 5.3-liter engines, it gets better ratings in city and highway driving than all of its rivals with similar-sized engines--at a time when every mile per gallon really counts. The 2008 GMC Sierra 1500 has one or two fewer gears than the Tundra. The Tundra--especially in top-trim versions--is especially competitive with the Silverado, as it offers a comfortable, classy interior and 5.7-liter V-8 that's more powerful than GM's 6.0-liter.
