Correct me if I am wrong, but I believe an additional benefit is that the tax rate on dividends is substantially lower than that of capital gains.
It does seem that recent changes have again adjusted the tax rate. In fact, based on more information[2], it seems long term capital gains tax is in fact lower (while short term is the same as dividend tax).
