Despite some flaws, I would say it's easily one of the best and most important fantasy series ever. It has some of the best worldbuilding in the genre, and a truly epic story that provides a great sense of fun and adventure.
The middle books drag, but most are not actually "bad" and they' don't seem nearly as annoying now that you don't have to wait five or more years between releases. You can run through them pretty quick, and get back to the good stuff.
If you like the Kingkiller books, I think Wheel of Time is probably a good fit for you. I've been reading the Rothfuss books over the last few weeks, and right away they reminded me of a cross between Wheel of Time and Wizard of Earthsea. I would say that the tone in the Kingkiller books, and the pacing, is very similar to Jordan's books, though the texture of the world is very different.
Edit// The Wheel of Time books also have a damn good magic system. It's not all that unique, but it's very well executed. There are a lot of variations, good limitations, it has interesting ripple effects on the whole culture of the world, and he never lets it become cheap.
