I'm transitioning from Finish Powerball tabs to Cascade Complete pacs, as the Powerballs are merciless about turning aluminum cake pans, etc., all manner of odd, patchy, dark colors. Plus, the Cascade Complete pacs do a better job with pots/pans.
Small benefits: The Cascade Complete pacs have no little wrapper to deal with. I've also found that Powerballs tend to disintegrate a bit when stored for more than a few months. I purchased three 90-tab containers from Sam's Club awhile back, and the tabs in the final container are noticeably "crumbly" when unwrapped.
Haven't tried Finish Quantum, but it's gotten great reviews from AW members who use it. At any rate, I'm using up the final 40-or so Powerballs I have left with loads that contain no aluminum pans, and Cascade Complete pacs for everything else. Just can't bring myself to throw out the remaining Powerballs, as they clean most loads very well.
