although i've had my eheim's for only a few months i must say that they are the best filters out there. i have not had the pleasure of using fluvals, but from what i have heard they are really easy to use, but not to say that the eheim's aren't as easy i cant say. i really love how quiet they are and how fast they filter out my 125gal tank. also they give you a lot of options of filtration to use in their filters. btw i have 2 eheim 2217 classic's running my 125gal tank.
