HeyaIt really all depends on your ultimate goal(s). If you want to have fun just choose anything you like, since the market is extensive.
RWS (Rider-Waite-Smith) is good because let's be honest it's easy to grasp and the symbolism is very straightforward.
I would recommend staying away from Marseille and the likes of Visconti-Sforza, because the imagery is not always straightforward, esp in the minor arcana dept. Would be extremely difficult for a novice. Off the top of my head at least a year should be allowed, even by the most gifted ones, before they get anywhere near being confident with these. Unless they are willing to delude themselves of course The problem is these are derivatives of playing decks, esoteric usage not being their primary function at all
A lot of decks are essentially Rider-based in that they keep all the Rider symbolic elements and re-interpret them in the stylistic vein of every given deck.
Robin Wood is a good one if you like pagan symbolism, also very Rider-based. http://www.aeclectic.net/tarot/cards/robin-wood/
Even Joie de Vivre is Rider based, at the end of the day http://www.aeclectic.net/tarot/cards/joie-de-vivre/
PS the only book on tarot one could ever want, at least for the first several months, is this http://www.hermetics.org/pdf/Waite_Tarot.pdf
