The Financial Comparison Builder

Compare these two (or more) companies financially and tell me who's the
stronger business.

Company A: [PASTE FINANCIALS OR KEY METRICS]
Company B: [PASTE FINANCIALS OR KEY METRICS]
Why I'm comparing: [INVESTMENT / COMPETITION / ACQUISITION /
BENCHMARKING]

Build a side-by-side on:
1. Size and growth
2. Profitability and margins
3. Efficiency and returns on capital
4. Balance-sheet strength and leverage
5. Cash generation

Present it as a comparison table, then give a verdict: who is the stronger
business on these numbers, on what basis, and what the numbers can't tell
me that I'd need to investigate.
