(I am a CSU graduate, so you know my bias.)
When you read breed/industry/trade magazines 99.999% (don't want to say always, because someone will call me on it.) of current industry professionals have graduated from one of the four schools listed above.
Each of these four has a certain aspect of beef production that they excel in above the others. If you want information about the strengths and weaknesses of each just ask.
