Well, my brother always tells me that the BR takes skills and the DMR doesn't. I proudly do not agree with that. These two guns are different in many many ways. Like, the design, range, ammo, scope and how it shoots. All of these explain why they both take skill. People tell me that if you shoot a spartan once with a DMR it will kill them in an instance. But, that's only if you get a headshot and that's rarely that it will kill them in an instance. Then they tell me it takes a whole clip to kill a single spartan with a BR. Well, let me tell you it takes a lot of skill to kill someone with a DMR. Personally I would go with the DMR. I feel like the range, design, scope and how it shoots really makes me want to use. For some uses I use BR but, not much. Just depends what combat I am going in to.
