Which phone should I buy?

Hi!
I want to buy a new phone where the camera is the most important thing. It should have decent specs so I can play some games and use standard apps like Snapchat, Facebook etc. I don't want to spend too much money. I have a list of phones that I am considering.
One Plus 3
LG G4
Samsung Galaxy S6
Moto G4 plus
Nexus 5x
You can also leave a comment if I missed a phone that you think I should consider.
