You can see in my signature I had the S4, Htc One and the LG G2, as far as the latter two devices ask me anything you want. The only two things I loved about the One was the look and feel of it and I liked the Sense UI with Blinkfeed. The G2 was a really cool phone, the knock knock feature is sorely missed after getting used to it for 2 weeks. The rear buttons are not too bad but it really is simpler and easier to have them where Samsung puts them, btw the One power button is a pain in the butt and there being only two buttons instead of 3 down below was just stupid.
So I really liked the G2 but in the end I had to return it because when wearing my polarized sunglasses the screen was impossible to see, also in certain ligt and angles I could see a grid of dots all along the screen. Lastly there was too much lag both playing games and simply scrolling around in settings. SO I revise my list to the Note 3 is number one, the Htc One number 2 and the G2 would be my 3rd choice, now if the Sony Z Ultra were out it would most likely be 2nd choice since it has no flash and if the One Max were available then it might just be first but its not.
Lastly G2 will likely see updates a year after the Note 3 and development will be much slower but most of its problems for most users can't be addressed by development, either you like the button placment or not, either you like on screen navigation controls or you don't and either you wear polarized sunglasses and use your phone while doing so at certain angles or you don't lol.
Me I like to use a phone with stock launchers and the features that the maker put on it otherwise might as well just buy the Nexus device of the year or Google editions, if a phone needs a replacement launcher and an ASOP rom just to be tolerable then whats the point?
