is canister filter better than power filter?

I always run both an eheim classic 2213 ,2215 ,2217 and an AC110. Its a killer combo the eheim classics run a ton of substrate pro (Which they come with) And the AC110 turns a bunch of water over through a sponge and takes care of 90% of the mechanical it seems.

i dunno whats the difference between eheim classic and ECCO, and its so expensive.
I just purchased an eHeim 2215 i think, from petsmart. Instead of using it on big tanks, i will be using it for a 29g for now.

ECCO 80 gals runs 5 watts, and cost more, while Classic 93 gals runs 15 watts, and cost less.

One question, how long do u clean up ur eheim 2215 filter? 6 months?
