Revan Reborn vs Darth Traya

All-out

Revan ashes her.

Revan and it isn't even a contest.

Revan as per views of Chris Avellone, and he is very likely to strike first (more tactically sound).

Revan does have remarkable defenses, and was able to operationalize Star Forge without getting stripped off his life in the process (Star Forge's consuming effect which killed many would-be operators otherwise). Revan was also proficient in the use of Drain Force (Knights of the Old Republic Campaign Guide); same technique which is attributed to Darth Nihilus in the same source. Revan had no issue with drawing strength from the Dark Side; he would us any Force power to his advantage, as long as it does the job.

revan sends her with a force push out of the planet

Traya gets annihilated.
