I quaere about Obito because we still don't know enough about Madara... It's obvious they both are manipulative, but the way how Obito uses people is similar to Light's ''style''. Obito manipulated and used Nagato, Konan, Yahiko and Kisame and he also tried use Sasuke. This reminds me to the way how Light used Misa, Rem, Mikami and Kiyomi... but who is worse?
