Should I get the Suros Regime?

Today at our friendly weekly merchant Xur he is offering the auto rifle Suros Regime. Some of you might be asking if we should get it or not. To be honest, I used it and it was fun, but I left it on the side for a long time now and didn't care to upgrade it until I faced a guardian in the crucible. He was using the Suros Regime and I was using my Vanquisher VIII, which can be found at the New Monarchy seller. The guardian totally nailed my a$$. With Suros fully upgraded against my Vanquisher fully upgraded I didn't stand a chance against precision shots. Even though my Vanquisher was fully loaded with 47 bullets and fully upgraded, I couldn't fight back when we are face to face. After this fight I decided to brush off the dust and get my Suros back in action. But Suros is a slow firing auto rifle. If you aim with it, the speed of bullets cuts in half, but the damage goes way up. So if it doesn't bother you that much, I would say the 23 strange coins is worth this amazing rifle. Good luck, and let us hear your thoughts about this auto rifle.
