Safer? Well, the blade going down creates more thrust than the blade going up because it "takes a bigger bite out of the air". So, the center of thrust is a bit to the right of the spinner. On a non-counter rotating twin, this means that the right engine center of thrust is further away from the longitudal axis than the left. So, losing the left engine has a slightly more adverse effect on performance than losing the right. In other words, you'll run out of rudder (to counter yaw) a little bit quicker with the left engine out, than you'll do with the right engine out. On counter rotating twins you eliminate this, which I guess can be viewed as safer.
