I can get it for almost-free when I'll extend the contract with my carrier. Is it worth it?

I don't really have money for Nexus 6P, but I can get the LG G4 here for quite affordable price. I like 5X looks, lightweightness, pure android and fingerprint scanner and personally would lean towards it instead of G4. But if there are some serious flaws on the 5X, I'll reconsider.

So, /g/, what do you think about Nexus 5X?
