My guess would be (having had the exact same experience): - greater autonomy and less micro-management for skilled jobs - more job security because you are difficult to replace

On the other side high skill jobs are more stressful because the stakes are higher and the techniques for success are more uncertain.

In my experience, high skill jobs are less stressful when I am doing something I have prior work experience and I have confidence in my ability. When I don't they can be extremely stressful.
