Btw I think that if you are truly enamored of the Golden Universal, you should go for it. When I started studying the RWS I never had much problems with it as the images are similar enough to the RWS that the meanings attributed to the latter can easily be applied to the former. Most beginner Tarot books use the RWS in their discussions, so I was able to use them in a general study of the RWS (which at that time simply complemented my Thoth phase).
But if you go into an in depth study of the RWS are keen on its symbolism, which the most instructive (for me) Tarot tomes describe in great detail, then you may long for a real RWS clone. The birds flying in the distance, the background and scenery, the color schema used, and even the direction the central figure is leaning towards mean something, and these may be missing or altered in the GU vis-a-vis the real RWS. But of course it would depend on the book you will use, if you are dogmatic when it comes to the cards' symbolism or if you're more flexible with them, if you even use books or if you're the intuitive sort, your deep delight of the Golden Universal weighed against your possible disconnect with the actual RWS, etc. In the end, of course it's your choice to make.
