The LG G4 is a former flagship. It seems to still be getting updates. Motorola has some useful additions to Android that make it a fun experience. I'd edge towards the g4 plus unless I'd be doing serious gaming or something. I think that the camera is somewhat better in the LG but the g4 plus is supposed to be good as well. You can do spec comparisons on gsmarena.com as well as check it their reviews. They tend to be quite thorough.
