I could try... Though, pls do note that I am just an amateur
tarot reader with huge interest... and that's all

Well, the Rider-waite deck comes very highly recommended for
beginners because of the pictures

The deck is filled with symbolisms that are easy to inteprete and
understand. Which does help one to remember what is on the card.
However, upon futher inspection, one can find and it had often been
repeated that every thing present in the card actually have a
deeper meaning. The hand positions, the colors, the facial
expressions, etc. are now not as superficial as it may have seemed.
Also, most importantly- to me at least, the minor arcana is fully
illustrated, unlike the Thoth or Marseilles deck.
Most of the tarot books available in the market makes use of the
symbols in the Rider-waite deck. Let's not talk about the guide
books for specific tarots, but in general. Usually one could find
books using pictures of either a few decks-which would include the
Rider-waite deck, or plainly of that deck only.
Faced with the variety of choices present on the market these days,
it's hard to make yourself buy the Rider-waite deck as it is
somewhat more... dull and... well, I don't know... not that
appealing? However, it is worthwhile to note that most of the decks
out there have taken their symbolism, and/or inspiration from the
Rider deck. Which means that some of the symbols have been
tempered/changed and the meaning will be different from what it is
supposed to mean in the first place.
However, I strongly believe that one should get the deck that
speaks to them. As that deck would usually prove to be more
personal, and much more valuable than just any other deck would.
Although if you are like me and simply can't decide (and also being
too broke to buy all that speaks to you... or too impatient to wait
any longer), the Rider-waite's the best way to go... for now.
Either that or you want to have a deck of tarot on hand whilst you
delve into western esoteric studies... Rider-waite, Thoth or
Marseilles is the one you'll be wanting...
Hope that helps
