Interesting thread.
For myself, I find that having a deck with images expands my intuition and allows my imagination to flow far more than a pips deck. Words can cage and mutilate thoughts, images are for me far more multi-dimensional and evocative. I agree that certain pictures can as well, and yet for myself if I'd started with a pips deck I would have had to rote learn key words with no context. As for images getting in the way, I find that for me the more images decks I get the more they help me to get my own image of the card. Now, this may differ from the interpretation of whoever wrote the first meaning attributed to the card, I don't care.
The RWS has pictures. For me, essential when I was a complete begnner. Also, lots of books use it. So again, for me, I wanted the deck to go with the books. Now, I also had a couple of other decks which I just loved, and comparing them with the RWS was useful. However, trying to learn with just a deck I loved and a book which referenced another deck - very hard. And Thoth? yep, tried that too, as a beginner Book of Thoth + Thoth = complete confusion and switching off.
