> consistently failing power buttons
Define consistently? This is a complaint I haven't heard of, and having had four separate iPhones generations for both myself and my wife I've never had a button fail. https://www.google.com/search?q=htc+power+button+failure https://www.google.com/search?q=lg+power+button+failure

Definitely phones have had problems with reception depending on how they're held, as Apple pointed out at the time. There's little doubt the iPhone problem was worse, however. Discussion: http://gizmodo.com/5589336/apple-antennagate-and-why-its-tim...
I have no idea which iPhone had "consistently failing power buttons" but I have little doubt you can find other phones which have had problems with physical buttons.

The trade-off for the flagship phone in case of iPhone is battery life - it is noticeably shorter.
