Malgus for dueling skill has gotten the best of Satele Shan twice, beaten Kao Cen Darach, beaten Ven Zallow, beaten Aryn Leneer twice, and held his own against the strike team in the False Emperor Flashpoint. Bane has beaten no one without orbalisks or a nexus amp ever, apart from trainee Sirak and dueled evenly with Zannah who has only beaten Set Harth
For telekinesis Malgus has blown away tons of duracreet and durasteel buildings collapsed on him, choked out the strike team sent to attack him, sent Hero/Wrath/Nox/Barsen flying, stalled a ship with telekinesis until the engines whined, sent hoards of people flying and still had enough lurch his ship while it was flying, destroyed ships by overloading the fuel canisters with force scream, cracked transparisteel with force scream, toppled a pillar with force scream, sent Aryn Leneer flying, ragdolled Jedi during the Battle of coruscant, and hurled a boulder that blocked a mountain path.
Bane has only broken tents, boxes, and killed Qordis, killed non force sensitives on Ambria, and blasted Zannah back with a force scream unaided and of his own power.
Malgus is physically stronger than Bane. Malgus has cracked a marble pillar, broken tables, kicked Zallow hard enough to smash through stone, shattered duracreet while jumping from his ship, smashed pillars dueling Adraas, smashed away heavy machine parts hurled by Kao Cen Darach, and sent Jedi flying with a single kick. Bane has only mashed a skull without a nexus amp.
Malgus has tanked thermal detonators with barrier, Bane has no barrier feats off of a darkside world.
