Used both, I prefer the Navage, cleanup and prep is actually pretty smooth and gets better results if I'm in the middle of a sinus attack which is when I primarily use it. If I'm doing a lot of dusty work I'll run a rinse and clean stuff out, amazing how effective your sinuses are at trapping stuff.

I've had the same experience as Nick and Seahawk, there's a trick to it - try adjusting the angle of your head up down and adjust the seating of the ports in your nostrils. It'll take me a couple secs to get the position right where it flushes smoothly, Navage won't really flow if you don't have a good seal.
