Jumpers

There will be no consensus. Only if you have identical cabling used for both will one be able to make a judgment in one's opinion which is superior. If the wires are not identical, then there is no basis for declaration of which is better. 

Change the brand and or model of wire and the entire affair is open ended again. 

I should have stated that I meant using jumpers of the same cable. 

Reading the post you seem to be asking whether using jumpers of the same cable is preferable to using a "shotgun bi-wire", i.e. 2 identical runs of the same cable to your speakers.  People can help with this by way of of advice as many have been through this but we will need some more info;

- what are your speakers, current amplification, and cables?
- why are you considering this? what do you feel you are missing currently?
- are you planning on purchasing a 2nd amplifier to do the shotgun bi-wire, if so, same brand/model or different brand or model?

Your question cannot possibly be answered without a bit more info...

One easy option depends upon your speakers; if you have more than 2 binding posts on the back of the speaker currently (you must or the question is moot), how are they "strapped" together per channel?  Did the manufacturer include simple copper speaker straps?  What are your speaker cables?  I found that, at least in my setups, that going to a bespoke set of quality after-market jumpers identical to the speakers cables in use at the time was always a good move but your mileage may vary.

Before spending money, it's best to lay out what you have and what your goals are so you can get some more advice (IMHO).
