 If you liked
Dragon Drive

 ...then you might like
Legendz: Yomigaeru Ryuuou Densetsu

I've enjoyed both of these animes quite well. Dragon drive is about several friends adventuring with their dragons soaring through the sky. Legendz also has a main cast of characters who are close friends adventuring around with the Legendz, where several of them are dragons as well.
If you like dragons and adventuring with in-depth storylines then you should most certainly give this a chance.
