They're both good ADR. Dr Clavel had both on deck but wanted to reaffirm my bone density. Said bones, once inside, were good, but confirmed also with another DEXA. I could have gone with either ADR, but ranked M6 higher last minute in my case due to blood metal allergy test which may not have been an issue at all but why risk? Nickel was reactive as well as chromium coming up close to reactive. And no articulation thus wear debris. That said Activ L is fantastic with excellent results.
As far as revision for M6, Clavel said they were easy for him. Bierstedt said same thing. Clavel told me revision tools for M6 make it pretty straight forward.
