I don't think it's really valid to compare two different cranks on two different frames, especially because "winter beater" sounds like a lot floppier of a frame than whatever you'd put DA 7710's on.
Unless there is some way to tell what's just crank flex, but I'd be hard pressed to believe it's not mental.
