U.5.
Word of mouth is all I can really depend on, I'm not too smart on electronics but from a U.'s standpoint I enjoy my iPhone. Nope I'm not a die hard apple person, or a tech geek. I just really like everything it helps me do. Maybe not what you were looking for but I don't have any experience with the other two phones you listed. I am sure they are good too. Good luck. If nothing else look at other people's reviews that have these phones. That might help.
