Depends on how much editing you do. When saved at moderate
compression, jpegs are fine for the original save. The problem comes
when you edit, resave (which recompresses), edit again, resave, etc.
If you print the image as it comes from your camera, with whatever
changes you do in the initial session, and do not save as a jpeg a
second time, you are unlikely to notice the difference. BTW, jpg
artifacts do not generally affect resolution much, they screw up the
color tones and color fidelity.
The jpeg compression is adaptive, and the size of a file depends very
much on scene content, so no single measure of resulting file size is
worth much.
