What type of 9mm ammo do you carry daily and why?

Help draw me into the world of 9mm ccw. What type of ammo and why. Why a 9mm over a .40 or .357 etc...

Please post nothing negative about the other calibers.We've all read just about as many caliber war threads as we wish to read. Just positive/negative stuff about your 9. I am specifically interested in recoil and control ability under quick fire. Possibly links to terminal ballistics in actual shootings would be great.
