I would say it depends how much you will drive it. Seems as though you have a lot of cars that sit on the shelf. If this will be another one of those buy the Durango, they are the most beautiful cars in existance. I want the 1/10 4wd car to just put on a shelf and look at LOL.
Honestly nobody can tell you for sure on those two. Not enough people have driven them yet. JQ will stand behind his car 100%, Durango hasn't been in the mainstream offroad market that much but when they do something, they do it right the first time. I would get the JQ car simply because of how open he has been with its development. By now we all know if there ever is a problem with THE car he will be the first one to admit it and fix it asap.
