Okami is good, but it's a lot blander than God Hand in just about every way. Putting them on the same level (or putting Okami above God Hand, for that matter) is pretty laugh out loud. It's like saying Touhou and Cho Aniki are on the same level. While they're both good games, Cho Aniki is just better because instead of lolis (who are pretty generic and overused) it uses bodybuilders who shoot protein-powered bullets and lasers.
Anyway...
Castlevania: 10/10. I've never seen a series as consistently good as this. The only time it started falling apart was from 2005 and after, and even then it still had its great moments.
