I've refrained from commenting thus far because I simply don't have a dog in this fight, but i'll add my hopefully objective opinion now.
The three bulls with their butts facing us are three different types, the one on the left is what I think a hereford should be, the other two are OK, probably suited for your market where larger heavier carcasses are prefered, but not the type for really tough conditions.
Of the two bulls you've posted the second one (the one that nobody likes) is by far the better bull, he is sound, well made and has a good long soft muscle. The bull with the big butt (the first one) is structurally unsound, very straight shouldered with a poor top line. He wouldn't have made it past weaning in my herd. Both bulls have good heads and eyes although the brows could have been stronger.
There is more to a good hereford than simply a dark deep red coat and goggle eyes. The Brahman and South Devon you've posted are far higher quality than the Herefords.
