All creatine supplements are similar but they have different absorption mechanisms.
Creatine HCL and creatine pyruvate are more soluble then creatine monohydrate and have a better absorption rate then the traditional monohydrate. Creatine pyruvate also supports transcription of mRNA, which signals the body to produce more IGF-1 during training.
Your best option is to use a multi ingredient creatine formula so you get the best of everything. I personally use Ancient Strength from n2bm.com. It is a blend of creatine monohydrate, creatine pyruvate, and creatine HCL.
