Advice on wheel upgrade

I currently ride a tarmac with Roval SLX 24 rims and DT Swiss 350 hubs.

I am looking to upgrade to fulcrum-racing-zero-c17-competizione or Shimano Dura Ace R9100 C40 Carbon Clincher. My question is whether either of the 2 mentioned above are a significantly noticeable upgrade On the Rovals and which set would perform better for 70- 100 mile rides with whatever hills I can find. thanks in advance of any advice.
