I would say any type of CEE (creatine ethyl ester) should be preferred over creatine monohydrate. You can buy a brandname type of CEE or you can get bulk powders at places like BulkNutrition.com or TrueProtein.com which are much cheaper. The stuff is really sour so make sure your mixing it in with your shake or something like crystal light to mask the taste.

If your not familiar with CEE you can read a good overview of it here.
