I have owned both. They are pretty close in clarity, IMO. The Morrow cabling may have a bit more upper end emphasis, but it's a very small difference. Straley cable produced a little more weight in the music than did the SP-3, I imagine due primarily to its larger wire gauge.
Probably Morrow SP-6 would be a more apples-to-apples match regarding effective wire gauge, but since Mike Morrow no longer publishes effective gauge it's difficult compare based on this criteria.
