Which creatine do you guys prefer for better gains? The kind you take before your workout, or after?

Ive been taking the kind you take BEFORE, i swear it helps me lift like 10-20% more weight than i could without it....I ran out one day, and went to the gym and had the worst workout ever.

However, most people ( i think ) and most research uses the kind you take AFTER workiing out.

Anybody used both and have an opinion?
