If I may mediate, although I agree with gregory that the actual content of the pictures is immaterial, as long as they look pretty, I have read Aeon say in the past that the Thoth deck does speak for itself as an independent entity. I think that the root of this discussion is whether Tarot evokes feelings and associations, whether or not it is in the context of "Tarot" at all.
I think it does, even laymen can understand images and what they are meant to evoke, if they just look. That, after all, is the whole point of art in general. If art did not evoke anything, it would not exist, or would not be art. Of course, the question of "what is art" is too big to be discussed here, but I think we all agree on the basic premise that the Thoth is composed of art. It is also a tool similar to a fork or hammer, but it the root of it, is pictures painted on paper. Even a fork or hammer evoke certain associations; Neptune's trident, Thor's hammer. A Tarot deck does so much more, and much more purposefully.
One may as well ask in an art gallery if the pictures are meant to be viewed only by art experts or laymen. Unfortunately, the state of the art world today is in a large part the former, but the Thoth belongs to the older generation of the latter, and the emotional connections are readily made, as in, for example, the RWS.
However, I still think the OP asked a very simple question which, if differently worded meant "which cards do you think are the prettiest."
