There are a ton of possibilities.  I'm looking for one that is known to effectively crank case ventilate (i.e. proper spring/vacuum rate) a typical 440 street build that has lower than stock vacuum levels due to cam.

I think they all do exactly the same thing pretty much in the same way, its how they are packaged, how many inlet/outlets they have, how they look, etc. that set them apart from one another. It is a passive system meaning it works with engine vacuum and internal engine pressure. If your engine does not make enough vacuum to pull a PVC valve open you might want to look at an evac system where you route a line down to the exhaust.

Totally not true.  They have different internal spring tensions and different pintle sizes to work with different vacuum levels.

I am sure that is true and since you seem to be aware of that I would then say figure out how much vacuum you are producing and get a PVC commensurate with that.

One wonders, why a man with apparently such an intimate knowledge of the device, should ask advice in the first place. Sorry we couldn't help you and feel free to lead on.
