Can you tell us why?
I'm looking to get a G2 but obviously as the N5 is very close to it it's a contender.
The benefits of the G2
Bigger Screen
Better Battery?
Better camera
Reviews seemed to suggest better speakers.
N5
Stock android
Edit: Forgot wireless charging, which interests me.
And just to confirm this now has kitkat?
Prior to the 4.4.2 update the G2 easily beat the N5 however since the update it's far closer.
Yes the G2 has a bigger screen and the battery is a beast, easily beats the N5.
However where the G2 falls down is the micro stutters that plague the device, also I noticed that the more apps you install on the phone, the slower it gets. Even using a basic thing like a calculator the G2 used to lag ever so slightly.
The N5 is easily faster and for day to day operations it's a joy to use and doesn't even stutter.
The camera on the N5 is slightly better as well - in low light situations...
I'd disagree with people saying that the speaker is as worse than the N5 I'd say it's slightly better having played the same track side by side.
It's slightly louder and more clearer and less tinny.
Anyway my opinion is subjective, some people prefer the G2 over the N5 and vice versa and there's a nice long thread over at XDA detailing just that, I prefer Nexus devices over other OEMs.
Finally the European G2 doesn't have KitKat yet as it's only just started seeding on the Korean model.
KitKat is due to arrive on the G2 around March according to LG.
