Good review. I ALMOST waited for the G4. If it had a fingerprint sensor, I probably would have. However, between that, the quick charge, the wireless charging, and better chipset, it was too much of a compromise to get an SD card (important) and removable battery (not as important).
Also, the gold S6E is beautiful, FWIW.
Great camera comparison here that I hadn't seen...thanks srkmagnus...Camera showdown: LG G4 vs. Samsung Galaxy S6 vs. iPhone 6 | Android Central
