I didn't really like ToMI's story that much, actually. It felt like it was going somewhere interesting (Guybrush lost a hand, human LeChuck seemed nice and it looked like there would be another villain instead) but in the end it kind of just went back in statu quo and that disappointed me.
I didn't like the first three episodes as episodes, and as far as the story goes I feel the end of episode four and the whole of episode 5 just ruined everything that could have been good about ToMI's story.
So in the end, we're left with "prevent a pox from infesting the Caribbeans" and "stuff that could have been interesting but quickly revert to normal at the end", neither of which seem specifically better than Revenge to me.
I guess it beats Secret, though.
