Round 1: Cheapness

Advantage: Google. Cheapness is determined by P/E ratio. The lower the better. Be careful of earnings near zero that skew the ratio, one-time gains and losses, and pasts that aren’t indicative of futures (the more dynamic the industry, the more this is true).

Round 2: Growth

Advantage: Google. Growth here is the trailing 5-year EPS growth rate. This trailing earnings growth helps put notoriously-optimistic Wall Street projections in perspective.

Round 3: Operations

Advantage: Google. Net margin percentage shows how efficiently a company turns revenue into profit. The more similar the business models, the more relevant the comparison.

Round 4: Balance sheet

Advantage: Amazon.com. As with net margins, the debt to capital ratio is most relevant in comparing companies in similar industries. In this battle we give the nod to the lower-debt company, but attention should also be paid to the cost of debt, interest coverage ratios, and the stability of the business (the more stable a company’s operations, the more debt it can safely carry).

Round 5: CAPS rating

Advantage: Google. A company’s CAPS rating is our community’s opinion of the stock. You can get more information on your stocks -- and our community’s opinions of those stocks -- by clicking over to CAPS area.

Each of these five rankings need more context to determine how these companies stack up against each other and bracket competitors Apple (Nasdaq: AAPL) and Cisco Systems (Nasdaq: CSCO). But these basic numbers suggest that Google is a better buy. It’s up to you, though. Vote for the winner in the poll located below the bracket.
