Between those two cards, pick the GTX1060 6GB. Please try and find some semblance in what you say on the forums,
Arif, the RX570 is not a GTX1060 6GB killer.
It's the same on the hierarchy chart. The RX570 might cost less for some folks but it still draws more power than the GTX1060.
Speaking of which, zakirh15, you've got a reliably built PSU at your disposal to power the entire system after you drop in the GTX1060 6GB? Pass on the make and model and the age of your PSU.
