IMHO all of the tiny pocket guns would make a lousy bag gun or nightstand gun.
The Tomcat is a pocket gun. It's perceived recoil is at least twice that of the CZ-83.
Of the 5 guns listed, I would choose the CZ first, followed by the Bersa.
The CZ-83 is a fully featured handgun, and I think it would perform well. It will deploy quickly, fire quickly and with accuracy. It may be the most capable 32acp handgun made today. It is not my personal choice for a nightstand gun (an XD9 Tactical takes that role) but it goes to the range very often, because it is just such a pleasure to shoot.
I actually also own a Walther PP as well as 4 Kel-Tec P32s. The P32 is an excellect pocket pistol, and yes, one time at a party I actually carried all 4, just for giggles. My friend asked if I was carrying a gun. I smiled and said, "Nope. I'm carrying 4."
32acp is definately not my first caliber choice. But it has its place.
