Boy, am I torn. I voted 357 and I suppose that is as honest an answer as I can give but the 45ACP and 38 Special also are near and dear to my heart. I shoot an AWFUL lot of all three. I picked 357 because, at the end of the day I am a wheelgunner and carry that caliber in my CCW gun. It is a great caliber, more versatile than most, shootable, and fits into compact sized guns well. Accurate, good long range capability with heavy bullets, just a wonderful cartridge.
