I've played with both, and even though they look like the same string (both from Germany but different color), they are different in one way. The CyberPower will give you a lot more spin. Both of them will go dead in 2-3 weeks and will have to be restrung, even if they haven't broken. It seems to be a very rapid process once they go dead, and you can definitely feel it go flat. You will lose the spin ability, and have no touch on the ball. CyberPower does seem to have more touch/feel than SPP as well.
