I liked everything and anything about tobi before he was known to be obito. I felt like after his identity was revealed, it ruined his image as a villain after they revealed his motives.
Tobi before he was announced as Madara , but he was a mystery. For example, when he encountered Kakashi, Naruto, Sakura for the first time and he was just messing around with them until the end where he left and he got a deep voice out of nowhere o.o

I liked troll-Tobi a lot, but as he is right now is pretty cool. Physically, he is one of the most bad-ass looking antagonists I've seen, and his nihilistic attitude isn't too shabby either.
I can't help but wonder how much of the troll-Tobi was a manifestation of Zetsu's personality, though.
