Oh, I meant nitpicking in a good way, it is something I enjoy very much. Still, all three decks are very similar in structure and in meaning. Let's take a rather unpleasant card I got today, the Seven of Swords.

The Golden Dawn title for this card is Lord of Unstable Effort, Netzach in Yetzirah, Luna in Aquarius. Crowley changed the title to Futility. The RWS card shows what appears to be a thief stealing some swords from an array that was there previously. The PKT describes this card as
Pictorial Key to the Tarot said:
A man in the act of carrying away five swords rapidly; the two others of the card remain stuck in the ground. A camp is close at hand. Divinatory Meanings: Design, attempt, wish, hope, confidence; also quarrelling, a plan that may fail, annoyance. The design is uncertain in its import, because the significations are widely at variance with each other. Reversed: Good advice, counsel, instruction, slander, babbling.
This passage, together with the image, would seem to suggest to me the very unstable effort the title suggests. Energy is missing, perhaps "watered down," no perseverance, the full potential is far from being used. Under these circumstances, efforts are doomed to fail with no stable base (a look at the card connected to all sevens, the Tower, would suggest this to be the case).

Now, the Thoth card shows six small small swords attacking a larger one, emphasizing the
futility of the endeavor, as they, marked as the planets, will never be able to overcome the larger sword, marked as the Sun. Since we are in the suit of Swords, this would seem to suggest unstable, scattered thought, unable to focus and unite to wield the sword of the mind in order to succeed. Once again, little good can come out of this, and our Tower is inevitable.
Book of Thoth said:
The Seven of Swords is called Futility. This is a yet weaker card than the Seven of Wands. It has a passive sign instead of an active one, a passive planet instead of an active one. It is like a rheumatic boxer trying to "come back" after being out of the ring for years. Its ruler is the Moon. The little energy that it possesses is no more than dream-work; it is quite incapable of the sustained labour which alone, bar miracles, can bring any endeavour to fruition. The comparison with the Seven of Wands is most instructive.
I honestly don't understand what the Hermetic shows, but it does conform to Liber Theta to the letter. This portrayal is rather less obvious than the two previous, and I must admit I understand less the choices made here. Certainly it is the least "user friendly" of the the three. Still, the similarity with the two other cards is still there:
Liber Theta said:
Two Angelic Radiating Hands as before, each holding three swords. A third hand holds up a single sword in the centre. The points of all the swords "just touch" each other, the central sword not altogether dividing them.
The Rose of the previous symbols of this suit is held up by the same hand which holds the central sword: as if the victory were at its disposal. Symbols of Moon and Aquarius.
Partial success. Yielding when victory is within grasp, as if the last reserves of strength were used up. Inclination to lose when on the point of gaining, through not continuing the effort. Love of abundance, fascinated by display, given to compliments, affronts and insolences, and to spy upon others. Inclined to betray confidences, not always intentionally. Rather vacillatory and unreliable.
Once again, futility, unstable effort doomed to fail, scattered thoughts, etc.
