I'm torn, because while the first saga had better storyline and plot, I was really taken with the second's depiction of magic and of the main character. Granted I don't have all that much exposure to fantasy novels in general, but the fantasy settings I've seen (including RPGs) seem to shortchange magic. You hear of long labors to learn spells, but when it comes down to it, it's not used for much. The second half of the Amber series really made me feel what it would be like to command forces beyond those of the natural world. I didn't care for the too-long traveling descriptions and such, but the workings of magic in that world were vividly depicted and very captivating.Chronicles of Amber was very good as well, although I much preferred the Corwin saga (books 1-5) vs. books 5-10.
If anyone can recommend other good fantasy books which don't just gloss over magic but treat it in an interesting way, I'd love to hear of them. ^_^ About the only other thing I've read that resonated with me was The Wizard of Earthsea.
And btw, don't let "10 books" scare anyone away from the Amber series. Each of those books is small. I got them all as a single hardcover-sized book, so it's not as huge as it sounds.
