Texas wins on cost of living, particularly housing. However, consider the specific cities within Texas. Austin is becoming increasingly expensive, nearing California prices in some areas. Dallas and Houston are generally more affordable. For pure software engineering job volume, California still leads, offering a wider range of specialized roles and companies. Growth potential is also strong in California, though competitive. Factor in state income tax; California's is high. If your priority is rapid savings and homeownership, Texas is compelling. If you value career diversity and potentially higher (but taxed) earnings, California remains a contender.
