I think Revan's proven himself more than Thrawn has. Yes, Thrawn was a genius, besting the New Republic time after time and thinking up some truly great schemes, but we've heard much more about how Revan bested the Mandalorians so utterly that they stood absolutely no chance. Add to the fact that if Revan learned it, he could use Battle Meditation and influence his troops, an advantage Thrawn could not counter.
well if the fleets were equal and no help offered, it would be like this:
Revan on Leviathan makes an unorthodox strategy, thrawn makes a great strategy, fleets meet, revan uses battle meditation(surely learned from bastila) destroys half thrawns fleet, thrawns eyes pop out of the sockets, revan boards a small shutle, invades thrawns flagship, makes it all the way to the bridge, puts thrawns eye back in the sockets, then pulls out his saber and anal rapes thrawn, which persuades him to give up.
revan wins
The anal invasion is a bit harsh... Settle down, man... lol
Revan would win. He was able to conquer the Mandalorians from a losing battle, and completely route them. He was a tactical genius, and though I am certain he could win without such help, Bastila and perhaps even the Exile would swing things into his favor. In any case, Revan had great foresight in battle and in politics. He wins.
