At Equal cartridge overall lengths, you have the same case capacities. The 458 Winchester advantage becomes the longer SAAMI throat when in conjunction with a 3.6" magazine. Pretty easy to get the 3.6" advantage with a Winchester M70 Classic with minor modifications.
A re-chambered 458 Lott, from a SAAMI 458 Winchester, with the CZ's longer magazine allows for more case capacity in the longer 458 Lott brass, at a longer cartridge overall length than the 458 Winchester can accommodate. Most evident the shorter the actual bullet's length.
Of course, none of this matters unless you hand load, or have someone load for your specific rifles.
Personally, the I like the 3.4" magazine loads in the 458 Winchester. I don't think they will be the cause of anyone being mauled or stomped into a bloody mush.
I have a CZ 458 Winchester / 458 Lott and a MRC 3.6" magazine one.
