yoda owns palpatine as shown by the ass kicking he gave out last time, only reason he stopped is because he was lightsaberless
mace owns tyranus form 2 is great and all but its nothing compared to maces vaapad.
Sidious never owned yoda in fact yoda threw everything he had right back at him and the resulting explosion is the only thing that kept sidious from getting chopped up, yoda was more then able to take everything sidious could throw at him. Sids also never owned mace even though he's a cooler charachter, sure he exagerated whining on the floor like the little bastard he was but truth be told he had no where near the lightsaber skill of mace, mace was considered probably the second greatest swordsman ever next to tulak hord and sidious was no tulak hord.
Yoda has already proven himself to be more powerful then Sidious, so Sidious would lose especially in Mos Eisley, what would Sidious throw at him? Sand?
Mace and Dooku now this is a tough one, Dooku already beat Mace once, one of the few that could. And he isn't weak himself an incredible duellist with a great style and a good command of the force. On the other hand Mace had at least 13 years of improving himself.
In the worst case for Mace he dies, but Yoda will still finish Dooku Jedi win
