Choosing an amphibious assault ship for a navy's actual duties

Which modern amphibious assault ship is the best design?

America class best fits American requirements; Trieste is the preferred option here for many Western medium powers, while Type 076 needs to be understood through Chinese doctrine.

The preferred amphibious assault ship depends on the navy's intended operations. America class fits American requirements, while Trieste is favored here for many Western medium powers over Mistral and Juan Carlos I. Canberra belongs with the latter as a Juan Carlos-derived design. China's Type 076 raises a separate question about the connection between its design and Chinese amphibious doctrine. A suspected difference between published doctrine and intended practice concerns fire support and coordinated fires, but remains an interpretation under investigation.
