Well if you don't like the exaggerated style I guess any of the Key anime works well.
(Angel Beats!,Clannad,Air etc.)
Elfen Lied..That shit was fucked up man..Akira was very similar I hear.(basically the same story.)
If you like the "School Club" stuff like Haruhi then maybe
Okami-san and her Seven Companions although it wasn't an amazing show and it was more of a Fantasy take(With the whole characters being based on fairy tale characters thing)then a Scifi like MoHS It also has your very Tsundere lead.(Okami even looks like grown up Taiga Aisaka)
Angel Beats! is also kinda "School Club" and Yuri is compared to Haruhi a lot. It is almost the perfect mix of MoHS's silliness and feel-good parts with Elfen Lied's deeper heart-wrenching tragedy.
Baccano & Durarara!! are great as far as characters go.
I know in Durarara!! Crispin Freeman does the voice for Shizuo in the english dub (He did Kyon in dubbed Haruhi and I think I have developed a man-crush on him comparable to Daystar and Nathan Fillion.)

Deadmam Wonderland if its as good as the manga
Well, It wasn't as good and in the english dub guess who voices Ganta?
Fucking Greg Ayres!
I for one can not stand that guys voice in anything. I am a person who always prefers dubs to subs but in this case I had to go and watch it in subs because listening to this assholes raspy voice made me want to kill myself.(He is also my #1 complaint with Angel Beats!)
