Replying to Nikon 1 J5 vs Sony A6000

Hi guys so im looking at getting a new camera as i find a gopro doesnt quite give me the quality in shot that im after. Im looking for my camera to do 60% filming. Ill be using a glide cam 2000 for stabilizing and was wondering if any of you guys have heard much about the new J5 or how it would compare to the A6000. i really like the J5 slow mo features but also like the a6000's bigger sensor. my budget is $700 so if theres a better camera out there for that kind of money id like to hear what you guys think
