How Does the GMC Sierra 1500 Compare to the Competition?
The 2021 GMC Sierra 1500 is a very nice full size truck if you’re looking for something that offers an upscale interior for the money, although reliability may not be as high as some competitors as it ages.
The Ford F-150 is another large truck which is available for about $3,000 more. Off-road performance is better in the Ford F-150, while the GMC Sierra offers more luxury for the money. We recommend the Ford F-150 since ownership costs are a bit lower as it ages, although both are decent trucks.
The Ram 1500 is a popular competitor, which costs around $4,000 less. Standard safety technology is better in the Ram 1500, while the GMC Sierra 1500 offers better off-road performance in the AT4 model. We recommend the GMC Sierra 1500 since it’s a more capable truck, yet both are worth taking a look at to see which you prefer.
