The simple reason I would first and foremost recommend a Marseille with regards to Hebrew letter correlations is that it appears to be intrinsically linked with that deck.
The Visconti decks display different and quite astounding geometrical correlations and perhaps have even incorporated therein some Gnostic heresies (as one of my friends seems to suggest in another place), but does not appear to reflect in any direct manner the letters.
Also, there is the additional complication in determining whether the Visconti even had twenty-two Atouts (major arcana), and a growing concensus, in the earlier days simply suggested by many, that has since become a more accepted view since Huck has made Autorbis's work known that the Visconti may only have had forteen, and later additions brought this to twenty.
If one is working with the Hebrew alphabet (or to be more precise the alefbeit), then a twenty-two Atouts set would at least, I would have thought, been desirable.
