By and large, I really like using ablative paint. The bottom is not as smooth as a baby's, like what you get with Baltoplate and a couple of days of burnishing. But good ablative paint like Petit ACP60 - now called Ultra SR I think - lasts 3 or 4 years and you strip it with a pressure washer.
And I can lose more seconds in a race by a single mistake than a baby smooth bottom will ever gain for me.
