I was just wondering if the Drenalin has the same cam as the Standard Switchback?

no.

What is the difference and is one better than the other?

drenalin cam is more aggressive and has more area under the draw force curve. One is not necessarily better than the other, they are just different. Depends on whats important to you to determine which is better.

Thanks I was wondering. I am thinking of getting the drenalin and I shot one last night and it seemed to have more of drastic let off than the Switchback. It seemed to have more of a valley I guess if that makes sense.
