It would be best to buy all six directly and use the drip, if you have a long period before you need the income.Why would you give a piece of the action to a stranger who needs to do nothing to collect your money? I own all six and have well over 1 million invested and have converted to a cash dividend as I have now retired and use it as income.
 If you had bought $10,000 each of the big 6 banks 25 years ago and reinvested the dividends, that $60,000 would be worth Approx. $860,000 now. As a group they have done better than Berkshire Hathaway over the same time period.
