Ganondorf and Bowser are pretty slow, a pretty bid disadvantage they have. I don't think Bowser stands a chance against anyone. However, he can fly if he uses his helicopter thing. Ganondorf, however, has been shown that he can only be killed by two things, the silver arrows and the master sword, neither of which Bowser or Ridley posses. This means that Ridley and Bowser cannot even attack him. So I'd say Ganondorf wins.
