Main Question or Discussion Point

Sorry, I am not a physics major - I apologize in advance if this question is ignorant or if this was asked already.

What would be the most effective as a Magnetohydrodynamics weapon?

Assuming normal ionized air, would a liquid (liquid silver and salt water) or some type of plasma (anything?) be better for distance traveled and / or electrical conductivity?

Or is something else better than either of these?

I was playing a science fiction video game where a MHD weapon was used and there was a debate among my group of friends as to what would be best.

I just wanted to know what really would be the best for this. Thank You!!!

MHDs are mostly used for propulsion, not weapons, they don’t work as well as rail guns.
But I prefer plasma for being accelerated by MHD, because I heard usually they have a negative resistance for electricity.
