A better camera app on the N5 would help make up for some camera shortcomings.  Focal is a candidate in this area.  It's a decent camera, certainly capable of taking very nice pictures in certain situations, but not on par w/GS4 & other flagship Android devices.  Maybe part of this is Google leaving something on the table so they don't ****-off any hardware partners.
Display and performance are areas where the N5 really shines.  User experience is subjective.  I've been on WP since day one w/the Focus, then my 920.  Also had a 1st-get Windows 8 hybrid tablet.  For me currently, Android provides the preferable user experience.
Also, my wife has a new 5s.  I've spent months trying to work w/sol'ns to keep devices on all three platforms "talking" and "cloud-synced" while balancing ease-of-use.  Calendar, shared docs, grocery list, DLNA sol'ns, XMPP,  VPN, etc.  If there's a barrier, it's usually WP that won't play nice, for various reasons.  I didn't think I'd say this, but today I'd likely choose iOS over WP if limited to one.  For all I dislike about that platform, it simply meets more of my mobile needs right now.  I'm hopeful that won't be the case at some point in the future.  I still have high hopes for WP.
OK, I digress.
As others have said, bang-for-the-buck, the N5 can't really be matched.  Best Nexus phone yet.
Hopefully this was more useful input that merely saying "it sucks because others say so"
