I think this might be the something-something-cssu3 kernel, the one that is partially based on older release of kp, but with less features (mainly overclocking and thumb2 patches)... I think it was created as a very early preparation stage for future possible kernel updates via CSSU. Either way, go for power kernel, it's newer, better, has more stuff compiled in and if you used kernel power before, it'll better suit your use cases
