So I have researched many topics on this but they seem to only refer to the fact that WHB interrupts way more on charge than DVS. But as far as the normal combos go, I couldn't find any information on whether the WHB still interrupted more than the DVS. If anyone owns both or at least knows a ton about them could you please let me know, because right now I have vile striker but I'd go back and get WHB if it interrupts better on combo because thats the worst part about the DVS imo is the lack of attack interruption.
PS - Before anyone says it (I know someone would) I am using these swords for fun, yes I know WHB can cause wolvers to dodge, yes I know DVS poisons, yes I know there are more effective swords.
I can tell you only this far: Only the last hit seems to knock down a Zombie while unleashing one full attack Combo with Vile Striker.
Unfortunally I only own this VS, but if I can help with testing it in a certain depth against a certain Monster at a certain difficulty at a certain Party size, then just ask and I will deliver that data.
