Will my car ride smoother if i get rid of my z-rated tires and get something like h?

YES

What's your definition of smoother?

The rating such as Z are speed ratings, which mean that after 130 mph the tire won't shread like the stock one can. The Z rated tires are generally reserved for performance or all season performance tires so handling and grip should definately improve.
