I've used incogni and kanary. I'm not a fan of incogni. They have a list of data sellers and blast each one with requests to remove your data, whether or not they actually have it. Additionally I've been asked many times to verify information they found to see if its mine. Its not, like not even close. Same last name but the first name, age, and location are way off.
Kanary's been much better about targeting my specific information for removal. Its more expensive but I think they do a better job overall. I'm definitely more confident in them than incogni.
