Ok, this threat seems to have gone too far. Anyway, i say the team 2. Sidious is mostly accepted as the greatest sith ever, and i think he could have some advantage (even though a short one) to Ullic or Revan, while Mace had also Vaadpad and shatterpoint, so he could endure much time against either Ullic, who was also a titan with lightsaber (let's not forget that he could fight a jedi knight with his lightsaber WITHOUT the force) or Revan (who is known to beat the best warriors of his time like Mandalore, Yusanis, Malak, etc).
I would also point out that Malak's statement about jedi revan>sith revan is discussible since he said in the Levithian that when he blasted Revan, he had already surpassed him, what this is most likely a lie, or he would have tried to face him in a duel for sure. Also the fact that he lost empored by the star forge is not on his favor.
So, i am not really sure that jedi revan>sith revan, in fact i think they would pretty much the same. After all, it's the same person...
