I went through this decision a short time ago myself, but it was only between the 9mm and .45 ACP. This was before I started reloading, but even so, my answer would be the same today. Even though I didn't own another 9mm gun at the time (I do now), I went with the 9mm. The main reason was due to cost to feed. Since I started reloading (before the great ammo crisis!), the cost difference really isn't much. Having said that, I'd STILL choose 9mm simply because the cartridge gains so much from the longer barrel, while the .45 ACP actaully LOSES velocity in the longer barrel. I don't recall the exact numbers, but I'm almost positive the 9 was MORE powerful than the 45 from the longer barrel. I'm certain that it was flatter shooting by a long shot, as well. I had not considered the other calibers in your survey though.....
