Not Darth Revan. He rarely did anything with his ship, apart from telling where to go. Also, that ship was the Ebom Hawk, which is not a cap ship and we already know its pilots.
DN had a great ship, but again, not really a pilot, just standing there looking menacing.
Sion briefly controlled a republic ship (and a sith one in which he got there presumably).
My best guess would be the Iron Forge, even if thats actually a factory, not a ship, but it was clearly commanded by Malak for a long time. (and non canonically by, Darth Revan afterwards)
