What's more canon, Labrinth of Evil or the Clone Wars Microseries?
Well, the Microseries was on tv and directly lead in to ROTS. Labrinth of Evil also directly lead into ROTS, and the author, James Luceno, got to read a copy of the ROTS script before writing the book.
Personally, I say LOE is more canon. But they both lead into ROTS but have different events happening at the same time. So I'd like to other opinions.
