My first reaction would be to call myself .30-06 because it is an all-american, do-it-all round, has been very dependable in past conflicts yet is still ready when called upon, lacks the sizzle (sex appeal) of newer upstarts like the .308 or .223.
Then I start thinking about 6mmPPC. Short, squat, not necessarily a powerhouse unless aroused, and yet very accurate and to the point.
Then again....my wife would say I am some sort of shotshell, probably 16ga, because it is not much in use these days, has no neck, my middle dimension is approaching the same as the other two, and I tend to be somewhat scatterbrained.
Gee, you tell me!
