Generally speaking, quantity over quality (length), it depends on what you're trying to learn though. Are you trying to learn construction? Do a fuckload of line drawings. Are you trying to learn how to render small details? Then you'll need to do a longer study to learn how to integrate the details into the whole image. etc. etc.
Make a schedule. Do both.

Both are usually necessary. Though you will lean towards one or the other based on your interests/goals/career. An animator has little need for long extremely accurate paintings, and an illustrator or fine artist probably will do more longer pieces (though likely not exclusively unless they are a photorealist or something).
