Well, at least prior to 2003 there was a strong incentive to prefer gains from stock sale since it could get long term capital gain tax rates (15% now, 20% at the time) vs. dividends which would be taxed as normal income. Since then however, qualified dividends are taxed the same as long term capital gains.
There's more to it than that. In order to pay dividends, you have to pay corporate tax before you can pay out the dividends. And that is almost 40% on the top end. So the effective tax of qualified dividends is more like 60%.
Alternatively, if you can stash money overseas in tax free accounts or invest the money back into the business to avoid taxes, then you only have the long term capital gains tax.
