 If you liked
Shijou Saikyou no Deshi Kenichi

 ...then you might like
Beelzebub

I don't think Beelzebub is worth watching if you liked Kenichi but if you liked Beelzebub you will definitely like Kenichi. They are very similar: humor, school, gangs, fights, training etc. No exploding clothes, ecchi or anything unnecessary like in some other animes that have similar settings.
