Not an android guy, but around the office, there is a concensus that G2 is actually better than G3, anf definitely better than samsung.
It's the software they say that drags galaxy down. G2 is smoother and well balanced (G3 throttles a lot due to QHD screen).
So G2 is not a looker, and screen is obviously not as nice as S4, but overall better package.
Someone correct me if I'm wrong.
Another option id Z2 which has awesome battery life, but camera is average, screen is not that good and there are software glitches on some firmwares and OS builds.
And of corse least attractive option for most is L930. Stellar camera, great AMOLED screen, good battery life, hassle free software, zero maintenence & crappy app store. I personally prefer windows because I couldn't care less about apps and everything a normal person needs is well covered (except banking, depending on country. In croatia, weirdly, banking apps are far better on WP, go figure).
