I'm going to go with the revolver. With the thorough comparison you did as far as size, concealability, speed on target, reloading, capacity and etc. and you still can't decide it sounds like you really want an excuse to carry an N frame. Go ahead and blame it on me, I know how you feel.

I've carried quite a few of both, in duty holsters, and the revolvers always won out. However I've never been able to comfortably conceal one and usually carried an auto, or at least a k frame, in plain clothes. I had an IWB holster for the Ns, but every time I pulled my gun my pants fell down. If you've got it solved and want to carry a big revolver, by all means go ahead.
