I have the 1200, and although maybe not the top of the line filter, honestly I think it does a decent job. Granted I have a Penguin 350 on the tank with it(72g) bowfront, but it does hold quite a bit of media. My water is clear, so much so that if I didn't know better, I'd swear the tank was empty. And this is with nine 4-5" peacocks. I don't consider the bypass to be a major issue, and it is plenty dirty when I clean it. 4 baskets will hold ALOT of media and allow for many options. I don't use the spray bar, but instead made my own return out of 1/2" CPVC pipe, which slides right into the supplied hose. Eheims are supposed to be good filters(I don't own one), so ultimately it's up to you. Just my .02.
