I wonder why would one choose Nexus 5 over LG G2 with little price difference and so many advantages-
Better screen(5.2 vs 4.95, I know resolution is same or a little less is G2 but Nexus 5 is not as clear as G2 while looked on angles, see reviews on youtube to confirm)
Better camera(13 vs 8 front, 2.1 vs 1.2 front), see the sample pictures for both
Better multitasking(multiple windows open at same time on a single screen)
Better battery(about 33% extra)
Better looks(This may be personal but I never liked too dull nexus 5)
Latest 4.4.2 android(I got latest android on stock phone which will be upgradable to lollipop
