Searching the forums for comments may be your best bet. Generally people who're happy with their ADRs stop posting. For that matter, you're going to be primarily finding posts from people who're having problems, at least in the post-procedure realm.

Ten years ago, I would have said that there was little indication that type of ADR had as measurable effect on outcome as did surgeon placement of the ADR, patient condition prior to surgery, and patient compliance with post-surgery recovery protocol. Last I paid attention to it, the M6L had some bad post-surgery problems noted - primarily with the surgical mesh. Don't know where that ended up since then.
