iPhone 5 still worth it?

As the title asks, is the iPhone 5 still worth it as of this writing? I know there are tons of theses post, but I would like to hear the most up to date answers. I usually don't stay with my phone for over a year or so, but I try to, so...get commenting please! :)

P.S. Is there anything huge that the iPhone 5S or 6 could bring to the table? (And that the iPhone 5 wouldn't get in a software updat? Or is it probably just:


-Slightly upgraded camera/13MP Camera

-More Colors(?)
