I hear a lot about the Dodal, Conver, and Fournier decks as being good places to start. The Jodorowsky-Camoin and/or CBD Tarot (by Yaov Ben-dov) are decks recreated by experts who have devoted their lives to the study of the Marseilles Tarot tradition and so might be worth picking up.
Disclaimer: I don't have most of these decks myself, as I personally find the woodblock print style to be, erm, aesthetically unpleasing and the colours of most of the decks too bright. Still, these seem to be the decks most people go for when they start collecting TdM decks.
That being said, I really, REALLY love the Tarocco Soprafino (Il Meneghello), which is as gorgeous as it is fascinating to read. And, of course, you've already mentioned Le Tarot Noir, which is hauntingly beautiful, as well.
You can also check out the List of Decks that People Have (
