Nikon 1 aw 1 vs sony rx100 iii?

Nikon 1 aw 1 vs sony rx100 iii?
Added (1). So, I have been wanting the nikon 1 aw 1 since it came out. The fact that I can take it anywhere with me (hiking, swimming, beach, mountain) is super.
But then I see Tim Kellner on youtube with this killer sony rx100 iii. And he is able to make some really great stuff with it. The fact that it is small and has the ability of practically a dslr is impressive.
So, basically, Idk which one to get. I love the durability of the nikon, but i love the quality of the sony.
Help ME GET THROUGH THIS
