Yes, it is faster than Claymore. I'm getting almost 0.7MH/s more out of each of my cards, not crazy but certainly better especially when you consider the lower devfee.

But the thing that has impressed me the most so far is how stable it is. This thing is like a rock, once you set it off you can just forget about it.
From the second you click your BAT file, and you see how fast the thing loads and starts mining, you'll instantly get a sense of how stable this software is.
Not just the software too, my GPUs haven't crashed once since using this yet, something that used to happen a lot with Claymore.

I was having so much trouble with Claymore crashing 2 - 3 times a day for various reasons, this is like a breath of fresh air.

My only criticism is that it doesn't seem to find as many shares as Claymore does. Of course this could just be bad luck but will keep an eye on it.
