I was thinking about this quite some time, yet i still decided Revan would win. Yes, i know that it sounds incredibly unbelivable, but think about it. Revan was killing ppl like Maul and Dooku when he barged on the Star forge. If u went dark side, u had to defeat 3 dark masters, which i presume could confront Obi-wan Dooku and Maul. Revan killed them in no time. He defeated 2 Terentatek, which were considered Jedi hunters and are imune to Force(now go ahead and tell me, that Revan sucked with sabers). Besides that, Qui-Gon and Dooku both faced 2 sabers, and it wasnt too big of a problem, so i dont think 3 of them would make such a difference when we are talkin about Revan. Did he, or did he not defeat the 2 most powerfull sith on Korriban? Without any problems, i might add. Besides, ure talkin about all the strategys, remember, who was a master strategist? Yep. Revan. Im pretty sure he could oppose any strategy, considering he brought victory to Republic fleet when it was in disarrey and on the verge of extinction(not defeat, since they were losing all the time) and that was against Mandalorians, who are famous warriors.
Besides, Obi-wan is pretty weak in the Force in TPM, so i presume he would be choked first. Maul would probably be stormed and incapacitated for a minute, which gives Revan enough time to chop Dooku, and then to finish Maul.
