I absolutely love the Seashore

The Seashore is a wonderful ship and I'm completely content to keep sailing on this ship. My question is, am I missing out by not going on other MSC ships?

Should I give the Meraviglia, Seashore or Grandiosa a try or is the Seashore similar enough or better than those?

I do plan on trying the World America or the new World class ship that will be sailing out of Canaveral. But is there any reason to switch up going out on the seashore??
