Like wise Vodo cannot break Gnost deffensives as they were described as nearly impenetrable and were capable of holding off two highly trained sith lords for the duration of a space battle.
Also Gnost can move so fast that non force wielders literally cant comprehend it so not sure how Vodo is faster.
As far as Im concerned this battle can go either way but it is going to be one hell of a struggle for who ever comes out the winner
