A6000 vs NX500 against the GX7? But I guess I don't really need a new camera...

I really don't need a new camera. I have a GX7. But i'm sort of bored and would think like to trade in the GX7 and change to another camera to play with.

Other than the EVF (I rarely use the one of the GX7), and the fact I don't care much for 4K video (basically never use video) which would you recommend: the A6000 or the NX500?

Or should I just stick with my GX7? How does it compare to either the A6000 or the NX500, is it just as good?

My usage is mainly travel & travel photos, photo walks through the woods, and long exposure night photography. Little to none on portraits, maybe a night with friends at a pool party, but nothing else.

If the GX7 is just as good as either of these two camera, i'll just keep it, but i'm basically looking for a reason to upgrade and just play with a new camera.

From what i've read I like that the Sony's sensor is basically full frame (???) but dislike that there's not touch screen so I feel like changing the focal point would be a pain in the ass.

On the NX500 side, I like their reverse sensor engineering which does really well in low-light? (don't remember exactly what it was but think I read something along those lines)

Thank for any opinions!

TL;DR - Have a GX7, want to play with a new camera. A6000 vs NX500? Or is the GX7 just as good as either of these.

I don't have either of those cameras, and have to ask: do you also plan to replace all your lenses? If I had surplus money, I would get a new lens rather than replacing an entire system.
