By To LOVE-Ru, what is it exactly you're into? there is many good sides of To LOVE-Ru and bad sides, which side you liked most and which least? without knowing it, i can't recommend you any anime. I've watched quite alot comedy, harem, romance and supernatural & superpower genre, so i guess i can find you a nice anime if you tell me what you're really looking for.
EDIT: PM me the response, instead of writing here. i'll be not watching this topic anymore.
