On typical medium-type conditions, my Chrome/Yellow drilled 5 x 5 (box condition, no XH) went a few feet longer than my Punisher drilled 4L (box condition, also no XH). The PG also seemed to keep its length better than the Punisher as the lanes broke down. I've always had better luck with the Power Groove on choppier conditions where I need to take the front part of the lane out of play, whereas the Punisher seems to work best for me either on fresher wet-dry conditions or shots where the track is broken down but there is still a decent launchpad in front.
