Just my two-bits worth.....
Cleaning and changing anything is a pain. I'd go with 2 filters. If one fails its really not a big deal in a well-planted tank. I have 2 Eheim 2217's on my 180g tank. Every three or four months I change one of them, alternating of course. But, if the maintainence of 4 filters doesn't bother you, go for it.
