I have only very few Lenormands but each is in my basket for a good reason.
The Blue Owl is clear, small and the book I learned with used it (Anne Biwer). It's really easy to read with.
The Pixie is nice and clear, too, and I learned to appreciate Colman-Smith's art better. I also loved the idea of the tin ;-)))
The Game of Hope is wonderful because it has German playing card inserts, too. Since I'm digging my way into the world of reading Skat cards, I appreciate that a lot. Besides, the time of the late 18th, early 19th century is one of my favorite times in history, and I like to think that young Goethe played the game with his friends.
The Blue Bird is still on its way to me but it looks very nice, too, and I heard it praised around here so somehow I bought it...
I don't want to collect too many Lenormands but there are some really wonderful decks. Wanderwust, Silson, Dondorf, Clair de Lune, Revolution... but first I have to dive back into Lenormand. And for readings, the Blue Owl feels most comfortable to me.
