The impression I got from Breach is that Grimm, at lest the types generally encountered, win by quantity rather than quality. They use wave attacks and swarms to overwhelm foes. Individually-dangerous Grimm like the Giant Nevermore and the Giant Deathstalker are a lot more rare and, from what Oobleck tells Ruby in Moutain Glenn, very rarely if ever initiate a fight unless the odds are very much in their favour.

Oobleck also made an intersting comment in Mountain Glenn that suggests strongly to me that low-level Grimm are dumb. It's only when they start getting a lot bigger and older that they gain a modicum of cunning (possibly even human-like intelligence). Indeed, Breach suggests that a normal Grimm wouldn't even think to move away from the scene of a fight to seek easier prey - the human who is most obvious and noticable i(even if that is only by fighting) s the automatic default target, even if there are unarmed ones running away nearby.

The point? The sort of Grimm that came through the Breach would naturally be the sort that a couple of cadets with heavy machine-guns could mow down like wheat. The smart, dangerous ones are the sort that will only be 'end of level bosses' and we've seen few of those in a fight so far.

That isn't to understate the danger of the Breach. Even mindless 'charge, slash, bite kill' Grimm would have killed thousands of civilians if RWBY, JNPR, CFVY and the others weren't there to hold their attention.
