If u r looking for something between note 2 and note 3 then i would definitely recommend you the optimus g pro. Trust me its the most under rated phone.
It has got a gorgeous display, large removable battery, external storage, a zippy processor and more than enough RAM. The lg stock rooted rom i use is amazingly stable and i dont really feel like m missing something.
You will miss the vast developer support of the s4, but its not a big deal if u r not a flash junkie. There r quite a few stable roms for it if u wanna try.
Go for it :thumbup:
