Kenshin is 95 episodes (plus specials, I think), 4 OAVs, and 1 movie total.
I like Dual. It's sort of your typical mecha/sci-fi anime, but I'm a sucker for those stories where the main character finds some deep-inner-supar-power after going through some tough stuff. However, this does not mean I in any way endorse this storyline being endlessly repeated within the same anime series (you know what I'm talking about).
Noir is a pretty unusual anime, actually. It's more of a drama and doesn't adhere too strictly to the anime style. Yes, the girls are anime girls. Yes, they have guns and they can't get hurt, but dammit, it's got a deeper storyline than usual.
