Free cash flow yield (FCF yield) show how much of cash that may be distributed to shareholders the business earns compared to its price on the stock exchange (including both: equity value and debt value or just equity). The higher is the yield the more payouts shareholders can expect. 

Free cash flow yield might be the best ratio for dividend stocks with high cash flow but it will be useless for growth stocks while rapidly growing companies focus on growth but not on cash flow and payout to the shareholders. 

There is no real difference which ratio to use: FCF yield or EV/FCF ratio (P/FCF ratio) because they show the same thing only the calculation is reversal.
