The guy who's actually been leading LANTERN since the AMEN attack, if not before then?
It is entirely possible that Andy is the sanest member of LANTERN.
Rae just became sane yesterday, remember.
So, in conclusion, I think Crazy Rae is the most competent member if LANTERN, despite the fact that he isn't actually a member.*
I'm kidding, of course, Crazy Rae is Bonkers.
