I was suprised something beat out hedge(Osage Orange ) ;D
White and red oak are just average for choices around here ;hedge , hickory ,locust are more used/favored. It may be the best hardwood you have in good supply but we stack it with hedge to make it burn better. Course if you don't have it to burn don't do much good either

Here are some weight/btu comparisons;
