Choosing the right one...

So I've been looking around all the rumors and previews beginning to surface surrounding this 'next' generation of Android smartphones. My question is specifically concerning the Nexus 5 and the LG G2.

Shortly put, I wish, I could get a G2 Google Play Edition.

At the moment, it appears, the N5 will be loosely based upon the G2, but will be cheaper and as such, not as technically good, hardware-wise. The battery difference alone is a major concern. Anywho, suppose one were to choose the G2 for it's specs, with the sole intention of rooting it and getting vanilla Android on it as fast as possible - would this make any sense? Would it be worth the sacrifice?
