Neither. I use a supercardioid dynamic combined with a magnetic pickup. This is because of deficient room acoustics. With an LDC the room modes are too obvious and SDC would be even worse.
The mag pickup provides a smooth bass response with no room modes and the mic provides the missing acoustic guitar sounds plus, if carefully positioned, enough room reverb so I need no effects. It's not a conventional acoustic guitar sound but I like it and I didn't need to treat my room. Check it out in my youtubes e.g.
