Assuming the same interest rate, which has the greater present value: i) an asset that generates a certain amount of revenue at the beginning of every year for 5 years or ii) an asset that generates a certain amount of revenue at the end of every year for 5 years ? Why?

Why would it be incorrect to use the yield to maturity on a 10 year discount bond as the yield to maturity on a 10 year coupon bond.
