Which Android phone should I upgrade to?

[AlphaKennyTime]

I think right now I'm looking at the S5 or Nexus 5. I've also heard a lot of good things about the Note 4 but the price is probably what will decide whether I get that or not. As long as it looks nice and it's powerful enough to last another 2 years (easily run new apps/games that will come out as phones improve) I'm ok with it.

I'm not looking for a phone with physical controls since I don't want to pull out a PSP when I'm just trying to look something up or send a text.
