El Cajon takes job market and schools, while Miami takes affordability and safety. The widest gap is crime index, where Miami leads by 43% — the kind of spread you feel in a monthly budget or a nightly walk, not just on a chart. Read the category rows as a filter: if cheaper housing would change your life more than a stronger job market, weight rent first. If you are moving with kids, weight schools and crime. If you picked a city after one good weekend, use the weather and income rows to test whether that weekend survives a full year.
