Nothing like a good bullet thread to bring out difference of opinions.
If shooting bonded bullets I prefer the North Fork, they retain weight extremely well and have been accurate in my rifles. Swift are a close second.
When using mono metals the TSX have performed well as have the Cutting Edge Bullet Raptors. The CEB is a terrible looking concept, but it a devastating bullet on big game.
A couple of other notes:
If you trust a PH’s opinion, I have not hunted with one that liked Partitions on buffalo, they all felt the bullet was not stout enough (An edit:At least the ones I remember talking with about bullets). Take that for what it is worth.
Develop confidence in your ammo or change it. There should be no doubt in your mind that your ammo is accurate and dependable.
Shoot a buffalo or hippo in the right place it will die, they are tough but will die just like any other animal. Put a bad shot in one it can become very interesting.
I also still believe in solids. Softs first, solids after unless I am using North Fork Cup points in my 470.
