What mode is your camera most often in? Why?

I know an experienced photog who swears by P mode...

He used to be a professional photog

He uses P mode most of the time, you can adjust A & S in P mode so why would you need A or S mode at all.

Plus in P mode the camera compares the scene with 30,000 stored images to determine the best exposure and there is no delay while you adjust your M adjustments.

PS: I also know an experienced club photographer who produces lovelly prints who never compensates in camera, he prefers to do any adjustments in post.
