I'm not sure what you're looking for here.
I'd give an example.
You said that some of the variants had 4x differences between cases.
From my perspective, if you found a hash function that performs up to 3
times better* than "crypto-alike" hash in majority of tests and is 1.33x
worse that "crypto-alike" in few other tests, it's something that I'd
consider as valuable option.
* - i.e. produces 3x less collisions at, say, occupation ratio of 0.7
