Kimber Kable 4TC vs Morrow SP3

So, since 2004 I have Kimber 4TC biwired run, they are the blue/black coloured,
For the past few months/year, the Morrow cables got my attention, I found a killer $125 USD deal on a set biwired pair of SP3 cables 2 meters per run,, they are like 2 years old.
Any suggestions to go for them?
