For my money, I prefer .45 ACP over 40 caliber or 9mm, and I prefer 9mm over 40 caliber. I like the knockdown power of a .45 the best. But as the article you posted said, improvements in 9mm ballistics make me like it over the (also sometimes-harder-to-find) .40 caliber. When the FBI and other law enforcement agencies starting going back to 9mm, that told me that times had changed.
