Which series in the Heroes Chronicles did you like the most?

I haven't even heard of 7 and 8. I think 5 and 6 are incredibly boring; I barely made it to the end. The plot in them is dull, but I've always liked Jelu. 3 and 4 are better, but the plot still leaves something to be desired, even in the fifth installment, the story is more interesting. And I haven't played 1 and 2, and I won't. Why would I?
