I like the buffalo bore because that's all I've tried
My blackhawk loves the 180gr hardcast buffalo bore. It shoots it very well. Be ready for drastically more muzzle blast and a little more recoil than your standard load though. Buffalo bore loads their stuff like the old .357's were loaded. They're safe for most guns.
I think the cor bond loads are a little hotter. I've never tried them because my gun likes buffalo bore so much and cabelas pretty much always have it. Its probably the cleanest and most consistent load I've tried outside of some very expensive self defense loads, but those aren't nearly as fun to light off as those big hot 180's.
Eta: and your thread is anchored because it has my handle in the title. Just letting you know.
