It's funny that in those rankings, they don't mention the LG G4's removable battery or SD card. As features for a phone, those are the one's that stand out against the S6 and Iphones. Although them ranking it third is a pretty big win for LG.
And I don't think you can go wrong with the Galaxy 6 Chuck. Really, as someone already pointed out, you can't go wrong with any flagship phone lately.
