I just re-read what I wrote about glossy vs. satin, and I realize I'm not expressing myself very well.
When I say the glossy cards are "less visible", which is a terrible choice of words, here's what I really mean:
Both the glossy and the satin images are exactly the same. If one were to take a photograph of them, they would be identical. However, small details are very slightly easier to spot on the satin cards, because if there happens to be a reflection on the glossy cards, then the small details on the images have to compete for your eye's attention with the reflections of light.
On the other hand, the glossy cards have an "ooh, ahh" shiny effect, similar to the hot stamped gold on some Lo Scarabeo decks, which would be very entertaining when using the cards with others, which is why I suggested the glossy cards might be better if you were doing lots of readings for others, along with their increased durability. The satin cards, though, might be better if you want a quiet, meditative experience. Maybe like the difference between a symphony and chamber music; the symphony is more of a crowd-pleaser, but the chamber music might allow you to pick out the composer's themes and counter-themes.
Specific concerns might override these considerations. For example, if durability is your highest concern, then the thicker glossy cards would be best. If having the cards be easier to shuffle and handle is a top priority, then the satin would be best.
Oh, and I agree with purple_scorp, you will be happy with either!
