Hey Raya,
There's almost no way to answer because people learn things differently.
I actually find the Thoth easier to read intuitively because you aren't hemmed in by the scenic minors that essentially illustrate a single interpretation of the Golden Dawn meanings, often forfeitng the others. This is also probably one of the reasons the Thoth has a rep for being a "deeper" or more "harsh" deck. The artwork is more a painting of a specific energy than a comic book panel depicting an event. I don't think there's anything less-complicated about the Waite-Smith, and I would lay dollars to donuts that those scenes are the reason the deck has the beginner-friendly, Insta-intuition tag smacked on it.
If by easy intuitive reading you mean: "can you study nothing and read the deck perfectly?," I think either the WS or the Thoth will disappoint there. I've said it in other threads but it's worth repeating: intuition and study are bound up in each other. I think both of these decks are complicated and challenging. Both can be read straight out of the box. Both are friendly, rich decks. Both require study. Both have elaborate esoteric underpinnings. Both were designed primarily for magical use, not divination. Both have expert artwork that tries to get at the Book T meanings. For the record, the Waite-Smith deck is based on the exact same underlying system as the Crowley-Harris deck: the Golden Dawn's Book T.
They are obviously different decks, because there are (strong) differences between the way Book T was interpreted by Waite, a hermetic Christian, and Crowley, a gnostic NONChristian. So studying the WS system can be equally as challenging and Qabalah/Astrology/Mythology based, with a primary distinction being Waite's coy nonexplanations. In many ways, Crowley is more faithful to the original Golden Dawn system than Waite and his deck more transparent (i.e. allowing polyvalent meanings to be intuited). In other ways he was tearing down some old models and replacing them.
The thing is the Thoth can work right out of the box OR you can start a systematic program of study and wait to read til you've mastered some material. That depends on how best you learn. If you know something about the deck, your intuition will grow out of your study. But as Similia and Formicida point out, as you read with the Thoth, you'll start to wonder about certain details and elements... then you'll go find answers to your own questions. So the study will follow intuition.
That's a very longwinded way of saying: yes. You can absolutely read it intuitively and it will blossom richly the more you pay it attention. I think you get exactly as much out of a deck as you're willing to put into it.
