The double tap connectors that come with the latest Eheim classics are as
quick to disconnect as anything. I like the no possibility for bypass
design.

The lack of a quick disconnect on the Classic series would have to
knock them out of the running for "best", though they are just fine in
terms of filtration.

There is also an Eheim Pro Series that lacks the push to prime feature
and backpressure indicator. They are otherwise comparable to the ProII,
definitely high end.
