This thread is a lol. Thm does more damage, I have compared it. Though having *one* Cnj to stick choke and magic eva. down is nice, even though Thm can do it too.
But to answer some questions, yes fire does actually heal him for small amounts (even using Fists of Fire on Pgl has the same effect) and if you want a speed run you're gonna want all DD as Thm and at most 1 DD Cnj and very little death.
