I've had them all 4 (losi,ae,nexx10,durango). For me the Losi is the hands down winner. You wont be able to push the ae without traction rolling and it is hard to work on. The durango is horriable out of the box, requires a lot of option parts out of the box to make it even close to the losi in durability, and is extremly expensive. the nexx10 is as fast as the losi and the cheapest but it breaks front end parts regularly. The losi out of the box will smoke any of the other three, is by far the most durable in a crash. It will require regular diff maint., but is very easy to work on. Just my opinion.
