In general, Super DMZ 2.0 is the stronger oveall mass & strength compound. Adrenolin says he gets better strength gains from the Cyanostane than the DMZ, but in most cases, I would say it's the opposite. Why? Cyanostane contains 10 mg Dimeth and 15 mg Cyano...while DMZ contains 10 mg Dimeth and 10 mg M-sten.
They both contain 10 mg Dimeth, so the only difference between them is that the DMZ contains an 10 mg M-sten, while the Cyanostane contains 15 mg Cyano. In general, Cyano is not considered a very potent compound in terms of mass and strength (although it is still stronger than Halo Extreme). On the other hand, M-sten is a very strong steroid...not as strong as SD was, but still pretty damn strong none the less. So, you 'may" get better strength gains from the Cyanostane, but I would say it is uncommon. In terms of mass gains, Super DMZ wins hands-down.
