OCW Ventress vs TCW Ventress

Standard shit. Which version of Ventress is better and who wins?

TCW.

I assume the OP meant to separate the continuities - otherwise this battle would not make any sense.

OCW smacks

OCW by far.

IIRC, OCW Ventress could effortlessly chuck around giant trees and send stone walls flying as projectiles, but also got lolstomped by enraged padawan Anakin and Count Dooku. OCW is more powerful, but TCW is more skilled.
