OEM balancer or fluid damper?

It's a moot point at this time since my motor has a fluid damper on it, but I was wondering what the opinion is. Is fluid damper a better way to go, or stay stock. My thoughts are that the harmonics have been disturbed when the engine is built and the OEM balancer is no longer tuned to the engine and won't work as well. I'd be very interested to hear different opinions.
