A \score block is a top-level expression, like \book or \paper.

A \score block may include its own \header or a \layout block, whereas
\new Score won't allow you to do so.

\score does not automatically create contexts (whereas \new Score
does) ; therefore you have to create one inside it.

{ c } is equivalent to \new Score {  \new Staff {  \new Voice { c } } }

Yes. Anything can be regarded as a "single" music expression (even if
it contains nested sub-expressions), see the Wagner example in the
docs.
