By Lubin Danilo, founder of Lubin Investment

Quality: which one passes more criteria
Eli Lilly passes 8/10 of our quality criteria, against 7/10 for Merck. The criteria are identical for both: profitability, revenue and free cash flow per share growth, share count control, free cash flow margin, margin expansion, return on capital, debt, conversion of earnings into cash, and cash conversion cycle. No weighting, no opinion: it is a count.
Price: which one is cheaper
Merck trades at 22.4× its free cash flow, against 53.7× for Eli Lilly. A lower multiple means you pay fewer years of cash for the same slice of the business. Mind the reflex though: a low multiple is only a bargain if the quality holds up. That is why we judge the two separately, and never one through the other.

How to decide
There is no "better stock" in the abstract, there is a better stock for a given goal. If you want the most solid financial quality, follow the score. If you want to pay the least for the cash produced, follow the P/FCF. If both point to the same name, the case is simple. If they diverge, you are trading off paying more for a better business against paying less for a more questionable one. The two detailed pages below give the criterion-by-criterion breakdown for Eli Lilly and for Merck.
