Mat, my friends. Mat all day, every day. I also quite like Rodel Ituralde and Talmanes. Perrin can be a bit boring, but I like him because he's an upstanding guy who manages to stay with one woman (who he marries) throughout the whole series. Galad is decent. Moiraine is pretty good too.
Not a huge fan of Min, or Egwene. I hate Cadsuane.
Back and forth on Nynaeve.
