Composition vs Prefix @

Question

Whats the difference between Composition @* and prefix @?

Composition[f,g,h][x] f@g@h[x]

Functionally they both seem to give the same result.

Compare f@*g /@ {x, y} with f@g /@ {x, y} – Carl Woll Mar 23 '19 at 00:25 — Carl Woll, Mar 23 '19 at 00:25

ClearAll[f, g]
h = f@g
h[x]      (* f[g][x] *)
h = f@*g
h[x]      (* f[g[x]] *)
