bi-wire vs jumpers

I'm sure the question has been asked before, but could not find it.
by bi-wire I mean a single wire terminated by four connectors at the speakers end.
if you had to choose, regardless of cost, which would you prefer, or which do you think would be more optimal in terms of signals reaching the speaker.

I was considering ordering the Crystal Cable's speaker cable bi-wire splitter instead of using jumpers.

what are your thoughts on this?
