I know Im late... its 2017 but i just want to clarify things here
Lupin III can disguised like others, copy their voice, act like them but not always accurate. he's funny; can get out of tough situations sometimes; he's easily charmed by cuties; got caught and held in a prison (many times) but still escape.
While on the white side, Kaito can do the same, Disguise; copy their voice; act like them accurately; he's cool; he's charming; and he can ALWAYS get out of tough situation; only few knows his real identity; he was never put in jail; he always escape; and Biggest difference between them is, Kaito uses Magic/Illusion to steal and entertain at same time.
So overall, the winner would be Kaito Kid in terms of Attitude and Performance is Thievery.
But if you're talking about Arsene Lupin the first because of the title's mistake, then it would be mystery because I dont know anything about that dude.
