Pretty straight forward question: of the two individuals to go by the Azrael moniker Pre-Flashpoint, which one, and which series, did you ultimately prefer? Jean Paul Valley and the sci-fi oriented 1990's version? Or the occultic Michael Lane from the late 00's?
Please note this is the previously published comic versions of both characters; we don't know what the new Azrael is like, and the Arkham version is a pretty clear amalgam of the two.
My vote goes towards Valley. I prefer the scifi twist on the Knights Templar in the Order of St. Dumas, as well as the setup of him having a "System" underneath his normal personality to conflict with. I also liked how his origin was unusual for a member of the Batfamily, considering he never had a completely normal life to begin with, considering he was literally bred to be a hitman and didn't even meet his father until the old man kicked the bucket.
Lane has some cool aspects, and a definite personality, but I never really liked his unstable mentality combined with a magic suit of armor. It clashed too much with Gotham to me, and the very occultic tone of the book wound up irritating me (you can probably guess some of my complaints thanks to my message board handle, but please know that I'm also a student of history, so stuff like "the 8th deadly sin is faith!" Just seems stupid to me.) I did read some of issues, and I admired the energy, but I'm one of the few who found the Crusader to be annoying just in general.
