I think Rodger has said it well enough for most of us.
I'm not a metalurgest, and don't claim to be one. (I didn't even sleep at a Holidy Inn Express last night) But we are speaking of cast iron rotors from a number of manufactures and when one asks for a 'better rotor' it's pretty hard to define.
The Cf of the package is based on the Pads, not the rotor. Of course a rough rotor surface would be interesting, but not practical. lol
One thing I did think of later which could be considered worth looking into is the center vent area vs. rotor wall thickness. The fatter the rotor wall the more heat it can absorb before being saturated, BUT this means less vent area too. Makes for compromise. I don't believe any aftermarket maker offers directional vaned rotors either, this would be considered a plus, however mostly in the high speed area.
While it would take extensive testing to show one brand of replacement to be better than another, it's more likely they are of equal value to the normal user. More often when someone says their brakes are so much better with brand X rotors they neglect to mention the new pads and hoses and ? that they did at the same time. When was the last time you heard of someone installing new rotors only?
Pick one you like (yes, with or without holes) and run with it. Just don't expect earth shattering changes in your brakng performance.
