Sofi likes Aviate, I personally don't.. It basically categorizes and divides everything thinking it knows better than me, duh, But it's very unique and simple, so it might appeal to a certain group of users.
As far as the Nexus 5, it just looks like a good phone. Sure, the battery doesn't look great, the camera samples just prove that it's another Nexus with an average camera - they put Nexus 4's CMOS into a G2 sensor (OIS) so you're basically getting N4-esque picture quality with very basic optical image stabilization and some enhancements here and there.
Still better than HTC One's camera though and personally if I had the HTC One, I was in the US and my primary need wasn't design I'd sell the HTC One, buy the Nexus 5, have the better phone and extra leftover money.
