I work in a small rural hosptial, but, over the years, I've done and seen a number of total hips.
Different systems, Zimmer, Depuy, etc have their own strengths and weaknesses.
Also, as with any surgery, pt selection is critical.
Over the past several years, different ortho docs that have come through, seem to me, to be using less and less screws in the cups.
Frankly, between bone cement and improvements in the cups, bio-ingrowth and all, cement/press fit seem to work just fine.
Never say never of course, the rep brings in the acetabular stuff when we do total hips, and I know he still brings screws along....just in case.
