Bradford vs Brangus is a toss up. Both have 3/8 Brahman so its about the same there. Brangus are easier to come across. You can run Hereford or Angus Bulls. I think the Char bulls do better across Bradford than Brangus.
If you are talking F1 Brangus vs F1 Bradford they will be 1/2 Brahman you will pay more for the Bradford if they start tiger striping. Again, I think the Char bulls do better on the Bradford than the Brangus.
We have both also. I can't say one is better than the other but as CB said, I do like the flexibility of the Bradford. As a general rule I like to sell the blacks and keep the reds.
