Best Bang for your Buck Water Cooler

Which CPU water cooler has the best performance/$ ratio

I want a 120mm RAD so I was thinking of these:

NZXT Kraken x60

H110

H100i

H100

ThermalTake 2.0 Extreme

Cooler Master Seidon 120MX

110 is 140mm.

SwiftTech H220. Throw some aftermarket static pressure fans on it and its definitely one of the top coolers.
