My advice is like Michellehihi's: pick the deck that appeals to you, on the basis of the artwork and the size of the cards and such. Whether the deck is an old or modern version, clean lines or messy & ambiguous, are also issues for some people. But I don't think there is a deck that's particularly suited to people new to the TdM.
My personal favorite is the Burdel-based Lo Scarabeo, the one with the white backgrounds and primary colors, rather than the Universal. It has a left-handed Ace of Swords, hilted swords, round-looking staves, fleurs-de-lys on the coins, and a mildly obscene detail in the the Queen of Staves found in some TdM decks. And loud colors. This isn't a suggestion for your own choice, but an example of the silly little things that might feed into finding a preferred deck.
As you already have the Camoin-Jodorowsky, my personal suggestion would be to get an older style, 78 card deck, either a cleaned-up restoration or a facsimile deck that is less altered.
Clearly, I need to research all the decks so I have a better understanding of the differences.
I've just gotten a copy of Vol 1 of the Tarot Encyclopedia. Time to start reading! ;-)
