I reload on a Forster Coax press expressly because I believe the die is more important than the press (the Coax lets the die be the star of the show). I evaluate dies based on the cartridge being loaded; some dies are better than others for specific cartridges for various reasons. In some cases, it takes more than one brand of die to optimize loading of a specific caliber. I think I use three brands of dies to load 458 SOCOM and 45 Cowboy, for example. Unless I find need for a specific die or die set for a caliber, I will purchase the best 2- or 3-die set for a caliber AND the corresponding Lee set containing the Factory Crimp Die. It also depends on your rifle and how a die forms the shoulder.
I find "the best" set by extensively researching the experiences and recommendation of others. Example: I just acquired a 375H&H. My study on this site suggested that a Redding 2-die set would be best, so I ordered the 3-die set (includes neck die) AND the Lee set that includes the FCD and micrometer seating plug. Therefore, I will full length or neck size with Redding and seat and crimp with Lee. Why the 3-die set? For practice shooting, I don't mind neck sizing. For hunting, full-length is best. For my 416Rem, I elected to duplicate the Redding/Lee combination.
On 458 SOCOM I full length size with Redding, expand with Lyman M-die, seat with Redding competition micrometer, and crimp with Lee FCD! How did I figure out that combination? The inventor of the cartridge said that's what he uses! (That's the value of extensive research)
I have a soft spot for Lyman dies but they don't have many African calibers. Hornady does and I am impressed with the quality of their dies, though their sliding seater sleeve is more gimmick than beneficial in my opinion. Redding is good, but not at everything. Note I am using Redding for long and wide cartridges, so that's going to be my recommendation to you for African. I use RCBS Cowboy dies for several of my BP cartridges and 45 Cowboy. Hornady and RCBS are probably tied for second behind Redding for African cartridges.
I have dies from CH4D, Hornady, Lee, Lyman, RCBS, Redding. I don't mind collecting die sets from all the manufacturers for a specific cartridge and experimenting. That's part of the fun of reloading.
