teka programmer or power commander


I am want to make some modifications to my bike but i have not decide which sistem to use to increase fuel, the power commander or the TEKA ecu programmer. i heard that with the TEKA i can increase the fuel at 10, 25, 50, 75 and 100% of the throttle openning, setting each % different to the other. the power commander only use three scales low, medium, high. Can anyone tell me which one have a better performance?
