If you're looking for really low noise, neither of these pumps is the answer - instead target a lower powered pump with less restrictive waterblocks (Swiftech 6000 series used to be my favorite for this, dunno about their new one).
If you want to lower your temps to match what an impingement block can do, instead focus on a larger radiator (or radiators). If you get the coolant temp down closer to ambient, you don't need to have as low a c/w block and can still have good die temps.
If you're not overclocking, it doesn't really matter, so long as you keep everything withing spec'ed operating temps.
