Tax implications? You mean because you will make more profit?

Regardless, DWACW is the best bang for your buck. If you plan on holding on to the stock for at least a few months, there are no disadvantages that I can see to buying DWACW and tons of advantages (by far the most profitable atm). But any of them are good investments (all substantially undervalued) so you can't go wrong.
