I am looking at getting a Eheim classic 2217. I was wondering if anyone has any experience with the classic series, and how they stack up against other filters?

I have a Fluval 406, a Rena XP3, 2 times Magnum HOT 250 and an Aquaclear 300 currently running spread out over 3 tanks.
Out of all of those I like the XP3 the most.

I am planning on switching the Aquaclear 300 with an Eheim classic 2217. Or I might move the XP3 to that tank and replace it with an XP4.
