Looking for a new phone, but I don't follow that stuff anymore (Sprint)

I have a Galaxy S4 that I like ok, but I'm not in love with it. It just feels kind of average to me; feels really cheap. I'd rather something metal or even something just made of a thicker plastic.

I have no idea what's new and good right now, except that the new iPhones just came out. I had like an iPhone 3 forever ago and it was fine.

I mainly use my phone to watch football when I'm not near a tv, stream shows and movies, text and web browse. I don't play any games or anything and I use my office phone for making most calls, so I don't really make many outbound calls on it. I'm not opposed to one of the huge phones that just came out, but I'm also not really leaning towards those.

What do y'all think I should be looking at, and what review sites do you like? I've usually looked at engadget in the past.
