I beg to disagree.
Yes, cows are cranky and can charge... But they are herd animals. You find them in heaps, with so many tracks leading to them that you could almost follow them with a white cane. You do have to hide yourself to approach, because they are always peeping and minding someone else's business, but that's about it.
If you want to hunt buffalo, as opposed to shoot buffalo, then the only thing that will do is the dagga boy, the old male that stays on his own or with a few like-minded grumpy gentlemen.
Here you'll have to track, sometimes for hours, and read the ground and the weather and the time and the moon, here you'll have to know the area, and the grass, and the water, and the quirks of the local buffs. Here you'll have to outwit an old bugger who is still alive because he's been through countless fights, with other buffs, with lions, with poachers. He's smart, not really worried but very quick to react if he picks your wind, and he's spent years peddling his testosterone to whoever came in the way, guarding his herd, cows and calves, when it was his time to be the boss.
An old bull has character. He'll challenge you, and make you day interesting...
Save some more money, wait a year or two, and look for a buffalo hunt in a wild area. The taste won't be the same.
