I honestly couldn't find a complaint with the Nexus 5. It's a stunning, fluid device. The only leg up in my eyes for the iPhone is the better app curation, but as someone who uses mostly web apps and Hangouts that's not a big demerit to me.

My biggest complaint is that it's just buggier than the Lumia I had before, or the iPhone 5 I had before that.

IMHO, it sounds like your biggest complaint is "it's not an iPhone".
