R1 Ultimate is very good. One of the best of the best. NH-D15, PH-TC14PE, Silver Arrow IB-E, FI-REEX Deluxe, .. a few more but I can't remember which ones right now.
As for AIO that are bette than air, Swiftech H220-X and H240-X and I expect the new EK Predator will be. But they are not CLC. Components can be changed and/or added.
