I usually use the lasso polygon tool, close trace the outline of the person. Where there's a sharp angle I go close, when it comes to hair and other things of a "fuzzier or busier" nature, I go a few pixels outside. Then paste to a white background and take out the extraneous with a white paintbrush. Finish with a small diameter blur tool for any minor bumps, and then copy that onto the image I'm "chopping".
