What CPU do you have an do you want to overclock it? As far as those coolers go, the AIO water coolers aren't much better than good air coolers. I don't think they're worth the price premium. I'd go for the CM Hyper 212 EVO out of those two.
Another suggestion is the Noctua NH-D14, I have that and it's amazing. It's only a few degrees behind the top AIO water coolers and significantly cheaper.

And Thermalright TS140 is just 1-2 degrees behind NH-D14, for the half of its price.
