Having owned them both, I strongly recommend them both. ;-)
You need a Decision Analysis Matrix (DAM) to perform Question Winnowing and Prioritization (QWaP).
DAM-QWaP #1: What RCM are you using now?
DAM-QWaP #1A: If the answer is "none" then get the Loricraft. You said it yourself. Cartridges come and go but vinyl is irreplaceable.
DAM-QWaP #1B: If you already have a decent RCM then it's a matter of which component will give you more enjoyment/dollar. That leads us to...
DAM-QWaP #2: What cartridge do you have now?
DAM-QWaP #2A: If it's a Lyra Helikon, Shelter 90X or someting of similar quality, the Loricraft will probably provide more enjoyment/dollar.
DAM-QWaP #2B: If it's a Grado Black, Benz Glider or something else that an Airy 3 would easily better, that leads us to...
DAM-QWaP #3: What phono stage and tonearm are you using?
DAM-QWaP #3A: If the phono stage has suitable gain and impedance and the tonearm suitable effective mass and resonance control, get the Airy 3.
DAM-QWaP #3B: If the phono stage has insufficient gain or inappropriate impedance, or if the tonearm is unsuitable for an Airy 3, that leads us too...
DAM-QWaP #4: Was the original question misguided?
