Hi there
I use all the decks above mentioned above, alot.
The BOTA deck by P Case is used as a coloring exercise to learn the color scales, which are similar but way more simplistic than the Golden Dawn color scales. Although Paul F Case (the founder of BOTA) has exelent tarot papers and techings avalibile and I highly recomend them and his cards,from a learning standpoint. Well more so his books and tarot teachings than the actual cards. The cards are very similar to Waites deck, and also recomended to be colored similar.
The Thoth- by AC and Lady Freida Harris is also exelent, and it is colored properly, in the sense of combining the paths and sephiroth with in the cards, although it does switch cards and trump's names, and 2 of the letters up (because of genders) the emperor and the star-so it is a different animal from the other hermetic decks out there, in a sense. This is a great deck, in my opinion for dream work with tarot path working because of the surreal type art Harris did with in it.
The Ciceros and older I Regardie and Wangs-use book T from the HOGD and the classic Golden Dawn color scales (which are very exact, color being one of the most important factors in the HOGD), so if you are looking for working with a certain (exact) color system this is the one. The HOGD is beyond strict with colors, very systematic. The HOGD teachings generally are an exelent foundation and have awesome teachings for anything "esoteric" though, so alot to offer in that sense too.
The Hermetic - by Dowson sort of swings toward a more purist alchemical deck with the engravings, not totally, but more so than the RWS, thoth or GD decks. This is also a great deck, especailly if you would like something Hermetic or esoteric, and the color scales arent as important. Great symbolism and iconogrphy in this one.
-There is also the Oswald Wirth deck, but qabbbalistically, the fool is Shin as opposed to aleph so every letter is one off, and this confuses me, dosent sit as well rather, but iconogrphy and art wise it is an exelent deck als, and has a classic marsellie style, if you are a TmD fan this would be a nice choice in that sense.
It depends is you are using the deck as a learning tool, how you would like to use your cards, and also visually, what you perfer. I use the Thoth, myself, the most at this point, but did heavily use the HOGD decks as well, espeacilly to build a strong fondation on esoteric tarot teachings, in conjunction with book T.
I also use P Cases way of thinking of the tarot, and BOTAs teachings with the table of trumps, cube of space, and general qabbalah studies, but not the deck per ce (still coloring mine)...P Case has some of the best esoteric books out there on the tarot.
At the end of the day, check some of the decks out, see what you like, try them out, go from there. What ever feels right to you.
