A photo with any camera any format is lossy. a picture taken with film or digital capture is a compressed version of what you saw as you took the photograph.
Granted a raw image probably has more information than the slightly compressed version of the jpeg file that most cameras make, but I would like to see you shoot 7 shots as fast as I can shoot 9 jpegs. And most people wouldn't see the difference between a shot that started out as RAW vs one that starts as a .jpeg after post processing any ways.
Now, I shoot a lot, maybe too much, but the type of images I capture usually are fleeting moment, and if I am changing flash cards every ten minutes or waiting for my buffer to clear then I am not going to get those moments recorded, not without going thru a lot more effort.
My point is... if you or your camera is not ready for the moment, I don't care how good your capture ability is, you are NOT going to have that moment as a photograph.
The impact of a photo taken at the right moment can totally overcome most deficencies in contrast, color, exposure, and grain if it is a truly great picture in the first place.
If it didn't then we might all be using 8x10 large format cameras.
