Well I have played all three and it's all in the realm you want to play.
Alb= Infitrator/Saracen = Good assasin = more spec points then the other assasins = the most versitile and alot of template option available. (Alb = Mythic's poster realm = don't have to worry about getting nerfed) = Nice RA's
Mid= ShadowBlade = average assasin but Norseman shadowzerker template is available = Fun to play. = Nice RA's
Hib= Nightshade = Good assasin (Was the best), only a couple of Templates available, only assasin with a spell line (2DD's 1cast, 1insta). Luri = small and very high in Dex = very nice damage + hard to hit and see. (Mythic's Redheaded step Realm = constantly getting Nerfed) :\ = So So RA's If you consider Remedy an RA.
I'm a tree hugger at hart so I went with the Nightshade. I like a challenge and DD's have saved my Elf butt more then once.
