Anything John Browning invented is the spawn of an unrepentant moral degenerate. Limited to the subject of cartridges, that includes the ACP's.
I'm not a fan of Jeff Cooper, J. Edgar Hoover, what they stood for, or anything in their legacy -- 10mm and 40 S&W.
9mm is boring and un-American, but that doesn't mean that I dislike everything that is. Some formerly polarizing cartridges like the 7.62x39 - a communist Soviet copy of a Nazi product that attained infamy as a weapon against American boys in Vietnam - can also be seen as an implement of liberation from imperial powers and communist dictatorships for a lot of other people around the world. I don't particularly like it, but I don't dislike it simply because some people used it for terrible causes. A cartridge can be used for good and evil and I don't find a cartridge's historical use as cause to dislike it. The .303 British is another good example of the same. It was used for the Massacre at Amritsar, but the British also wielded it in leading a moral cause against Nazism when Americans would have been apathetic to the wide-scale slaughter of Jews and many others.
They're all just little brass cones with primer, powder and a bullet. Since I reload everything I shoot and I'm only restricted to the guns' pressure limit or anything less that won't result in a squib, and not SAAMI specifications, the main factor determining the type of performance a cartridge provides is simply the size of the brass cone -- the diameter and the volume. Of course, there are other non-cartridge factors like the barrel length. Cartridges generally have characteristics with respect to headspacing, like rims, belts, shoulders, or mouths, and I find some preferable to others in certain types of guns.
