Stock (regolith) or KSP Interstellar for atmospheric extraction--opinions?

[seanth]

I have a part meant to be a resource extractor that would pull in atmosphere's from planets and allow me to recover various gasses and water vapour. I'm trying to decide whether to use the stock PLANETARY_RESOURCE way of doing things, or the ORS ATMOSPHERIC_RESOURCE_DEFINITION.

The stock method has the advantage of being stock, so everyone would have it. As far as I can tell, stock's MinAbundance/MaxAbundance and ORS' abundance values would have the same end result: I assume the dll does a calculation taking the % and the atmospheric pressure of the planet to provide a value. So a value of 20% for a gas in Kerbin's atmosphere would be less than 20% for a gas in Eve's atmosphere, and the rate of recovery would be slower on Kerbin vs Eve. Yes?

What is not clear to me is how the parts would differ. It seems like using ORS and KSPI, the part could use the ISRUScoop module and be able to automatically recover all the gasses with ATMOSPHERIC_RESOURCE_DEFINITIONs for that planet. If I understand stock's ModuleResourceHarvester module, I'd have to define a module for each Resource name that has a PLANETARY_RESOURCE. Is that correct? I need to define a PLANETARY_RESOURCE and a ModuleResourceHarvester module for each of those resources?

So, for Earth, I would need to define planetary_resources and moduleResourceHarvesters for for each of the following:

Nitrogen (78.084%)

Oxygen (20.95%)

Water (1%)

Argon (0.9340%)

CarbonDioxide (0.039%)

Neon (0.001818%)

Helium (0.000524%)

Methane (0.0001745%)

Krypton (0.000114%)

Hydrogen (0.000055%)

And on the part with all those moduleResourceHarvesters, I would have to activate one at a time to collect them all?

Is what I said above correct? If so, I am inclined to use the KSPI way of doing things since it would result in fewer buttons for the player, and would be easier to configure at the part level.

I'm curious what other people have to say, though.
