Would 100% suggest going the basic OAuth route with FB, and not relying on their SDKs whenever possible. Been bit by Friday-afternoon-PST deployments that wreak havoc until work starts Monday too many times :/
It's not exactly what you want, but just yesterday I made AccountsJS work with Facebook OAuth.[1]
I was glad today when watching this newsline, to have avoided the facebook SDK.
I think OAuth is usually better because every major provider has some version of it and so you basically can implement them all the same or at least in a really similar fashion.
