EER is just an active bistatic sonobuoy. They use an explosive charge instead of an electronic transducer to create their "ping." Informally they're called "bangers," by P-3 pilots and they're definitely still used. One of my gripes with DW is that they don't model bistatics at all.
The biggest obvious advantage to them over DICASS is their higher source level. That means a higher detection range and more efficient search rate. There's other more nuanced advantages to them as well, but I'm not really able to discuss them.
DICASS ultimately, aren't very good for searching a large area for a difficult to detect target. DIFARs will probably never really get much range at all against a quiet target, and are basically useless for searching a realistically sized search area in real life.

A person I play DW with is trying to convince me that EER is a sound tactic to hunt a submarine but I fail to see exactly why.
What can EER achieve that a field of passive/active sonobuoys + p-3 can't achieve ?
