While the .357mag is my favorite . . . . . . in a levergun, it's not even close as a favorite in a pistol. That's because the .357mag is primarily a revolver caliber and with their high bore axis and inverted cone shaped grip, a revolver is far more difficult to shoot accurately rapidly than a semi-auto is.
The high bore axis produces more muzzle rise torque and the inverted cone shaped grip make it much harder to resist any muzzle rise. So together, both work to produce dramatically more muzzle rise for the same recoil forces than that of a semi-auto.
My choice for my all around favorite pistol caliber is my custom G20L in 10mm. My hot 165grn 10mm handloads are larger, heavier, and produce a slightly higher velocity in my 6" Glock than my equally hot 158grn .357mag loads do in a 6" 686.
This results in significantly higher muzzle energy at impact. Further, I can easily control the muzzle rise of even my 'nuclear' level 10mm handloads while the wrist snapping recoil of my hot loads in a revolver are extremely difficult to control.
Finally, I can also load 180 or 200grn hardcast 10mm loads for larger, more dangerous game than my hottest .357mag loads can attempt.
