I suck at taxes, and I suck at math, but I'm curious... a qualified dividend ETF (like SCHD) pays less yield, but is more tax friendly. A covered call ETF pays higher yield, but is less tax friendly. So which ETF is preferable in a taxable account? Which ETF produces more income (less taxes)? If the answer is the covered call ETF, then why are people always preaching for qualified dividends in a taxable account?
