Portrait lens: - Beautiful bokeh
- Renders skin tones nicely
- Good working distance and FoV for pleasing perspective and distortion characteristics
- Has a lot of character in the way it renders people, colors, and OoF areas
Macro lens: - Highly corrected
- Brutally sharp (not good, as it renders all blemishes, impurities and zits on the person's face. It even renders any differences in makeup application)
- Allows really high magnification (main reason for owning a macro lens, not really needed for portraiture)
- Clinical, lab-like rendering, with next to no "lens character" (portraits generally require some mood, feeling, which is harder to create with a dedicated macro prime)
Yes, you can use a macro lens for portraiture. You can use a fisheye lens, as well. The question is just what you want, and which lens gives the closest, best results. You can use portrait lens with bellows or extension tubes for macro purposes, but the photos will not be as sharp, highly corrected as using a dedicated macro lens. Of course, these days you can use instagram-style filters and give any photo some type of "character", but that's a whole other can of worms
