I think which method is most effective varies by person, and that for ANY method you will find someone who swears by it and someone else who insists it never works. 🙂 I've heard the same story - this is ineffective, switch to something else - for oral, injections, gel, and even implants. I'm sure the people saying so are telling the truth for their own bodies, but people are different.
Anyway, I've been on patches from the start (and a super low dose to boot) and was outed at work within the first four months by the changes coming so fast and dramatic. By six months I couldn't get anyone to accept my male ID as me anymore and was a curvy C cup. So patches CAN work fine, and the only way to find out which method is best for you is trial and error anyway.
