Best cities in Texas to raise a family ?

Sorry for the long question but with California falling apart we are strongly considering moving to Texas. Which major cities and it's suburbs are the best to raise a family - uming we will have job security. Coming from the Los Angeles area anyplace else looks like an improvement! High taxes (with more to kick in next year), high housing costs, marginal schools - unless you want to pay for private. We're fed up ! Any suggestions would be greatly appreciated.
