Not sure real sure the "all music is subjective" statement works, (both musical notation and sound physically exist). It may be more reasonable to assert that opinions, (which often can be chock full of prejudices and misconceptions) are subjective.
The assumption that there is a best jazz guitarist at any given moment requires some big blinders. To claim there is a best jazz guitarist ever is pretty rich. Critical thinking / epistemology issues aside... this site has a couple of pretty extensive favorite guitarist threads... lately i've been trying to get pretty much any recording w/ Marc Ducret on it.
