I've played both and prefer 3D world. However my 5 year old finished Knack with me and wanted to play it again, he doesn't want to finish 3D world with me. The difference, in Knack I can help him stay alive, in 3D world he keeps dying in the later levels.
He greatly prefers Lego games over either, even Toy story 3 toy box mode over anything Mario.
