For shooting at the range and self-defense, 9x19mm, 5.56x45mm, and 12 gauge.

For flexibility (e.g. reloading, especially with unusual payloads and charges) , .357 Magnum, .308 Winchester, and still 12 gauge.

These are more a function of the guns I own for these calibers than the calibers themselves though.

I really got into 40 S/W for a long time.  Still love my glock 23 which I had robar do a grip reduction.  I guess I bought into all the 9mm not being powerful enough I guess over a decade ago now.  Thing is as I kept shooting and was into concealed carry I learned I shot 9mm far better.  Faster and more accurately. 

so after years and spending more money than I needed to buying guns I thought I would like but in reality didn't work well for me.  I like what I found works for me.

9mm sig sauer 239. 
glock 23
s/w #442 .38
mossberg 500 12 gauge.

(And you thought that icon was some sort of secret code.)

Shotgun -  12 guage
General pest (inference intended) elimination -  .223
real damn accurate military rifle shooting -  6.5 x 55

Teach your neighborhood pre-teens to shoot caliber - .22 lr
Semi automatic rifle for drive hunts - 9.3 x 62
Favorite caliber to impress the young 35 year old hottie next door with what style and class you have (OK OK, it is the rifle not the caliber, I will admit it) - 9.3 X 74R in a hand made Ferlach side by side exposed hammer double rifle.
Favorite caliber to take to the end of the world as we know it when you can only take 1 rifle - 22 mag in a bolt action rifle.  You can fill your pockets with a lot of them, they will do what they are expected to do, and it will allow you to feed and defend yourself.
