Well, there's a few reasons why I prefer recirc's to normal nw's. One its a must for me as i don't have an ato and my sump is a rubbermaid with no baffles and water fluctuates. With a recirc, water fluctuation does not matter. Another advantage is it is very easy to fine tune and once fine tuned its set, never need to mess with it again. The third reason is instead of pushing 800gph out my output, i'm only pushing around 200ish so no noise, or salt splash AND the biggie, 4x's the reaction time so more time to doc's to bond with air. Other than that, nothin else really comes to mind. ; )
