Hyper 212 evo vs. Noctua NH-U9b SE2

Hey guys!

I just want your opinion on these two coolers, which one is better?

1)      Noctua NH-U9B SE2

2)      Cooler master hyper 212 evo

I will be using the fx-6300 with a Gigabyte GA-970A-UD3.

They are in different price categories, of course the one that costs $20 more is better.
