With 17 years of reefing, I've tried just about every product out there, commercial and homemade... and I can honestly say that nothing eliminates Aiptasia entirely once they're in your system. You must work to keep on top of the problem regularly... you can keep them down significantly but they will come back if you aren't vigilant. I've found no difference in any of the commercial products. And peppermint shrimp couldn't be bothered. I haven't tried butterfly fish however, for fear of them nipping my coral. And filefish??? With those teeth? Fuggetaboutit.
