I own both myself and the G2. While the displays on the G2 and M8 are great and are by no means slouches, the AMOLED on the S5 is just stunning. The best on a mobile device I've ever owned. I do enjoy the back and it feels well construed. I went ahead and added wireless hotspot to my unlimited plan for another $30. I did this for more than just having it on my S5, the only device I own that isn't rooted but wanted to throw that out there for those who are worried about it affecting their unlimited data and don't mind paying the extra cash.. It only brings my bill up to $120 so it's acceptable for me. I love my devices and usually hold on to all of them but with S5, I planned on giving it a test run as I'm in love with the M8 and will not be parting with it anytime soon. But, I didn't count on my love for the S5's display. I'll be keeping it as well.. At least until the G3 comes out. A Galaxy device is like money in the bank. Great resale value. Owning all the devices that I do and cruising all the threads, it's obviously, as we all know, personal preference. Just keep at the reviews and find what features are most valuable to you.
If all my devices were held hostage and I was only allowed to keep one, it would be none of the above. It would be my developer edition Moto X, that is covered by warranty while being unlocked, rooted and running a custom ROM based the stock Moto UI.
Sorry for the novel, I always end up rambling.
