Each of them has their own Technologies: Price vs Performance is the most important attribute to pick a graphic card...for example Nvidia has PhysX and they were the first...and do note that most game developers adopt Nvidia as they have additional physics effects...whilst Gamework Technology is present too...and G-Sync and Shadowplay not to mention... AMD also have pretty techs... AMD was more or less well recognised with bad driver support. Do note also Driver problems with Nvidia (such as Shadowplay) However there's a "brand war"... if you require any exclusive technologies[example: a FREESync Monitor but not G-Sync Compatible] , that may alter your decision. Nevertheless, both RX 480 and GTX 1060 provide value for money. If you are finding more on full HD, both cards will suffice. If looking for more grab the GTX1070 or GTX 1080.
