AMD by far hands down are better quality and fit,thicker metal,more crisp lines ,if you have just a driver,not a high dollar car,you can save few bucks,but in the end you'd still have to spend time to install either parts, so there will be some minor body work,it's just the Goodmark sheetmetal is thinner,some of the vendors who carry Goodmark will lie and say that they come from same source just different packaging, they are full of BS,
