I voted with my wallet and got a CZ 97B 45ACP to take the place of my Browning High-Power 9mm.
One of those two is probably the best, depending on if you are more comfortable firing a 9mm or a 45ACP.
For me, the developmental evolution started with the S&W model 39, which is a single stack double-and-single action 9mm, to the Browning High-Power, which is a double stack double-and-single action 9mm, to the CZ which is a double stack double-and-single action 45ACP.
Although if you ask a LEO he/she will probably say the Glock 17 is the best. It all depends on what handgun you are the most proficient with, and this varies by person.
