I think it is less of a problem than it used to be, but historically PTFE-lined hot ends have been prefered for budget machines because they are more forgiving if all you want to do is print PLA. When everything is working right there should be no difference, but when things go wrong, not having plastic stuck to the heat break makes it more likely that a beginner can fix their own problem.
