How does germanic culture compare and contrast to roman culture

These include the kingdoms of the Visigoths (in Hispania and Gallia Narbonensis), the Ostrogoths (in Italia, Sicilia, Raetia, Noricum, Pannonia, Dalmatia and Dacia), the Anglo-Saxon kingdoms in Sub-Roman Britain and finally the Franks who established the nucleus of the later "Holy Roman Empire" in Gallia Aquitania, Gallia Lugdunensis, Gallia Belgica, Germania Superior and Inferior, and parts of the previously unconquered Germania Magna. 
The cultural syncretism of Roman and Germanic traditions overlaid the earlier syncretism of Roman culture with the Celtic culture of the respective imperial provinces, Gallo-Roman culture in Gaul and Romano-British culture in Britain. 
Early Germanic law reflects the coexistence of Roman and Germanic cultures during the Migration period in applying separate laws to Roman and Germanic individuals, notably the Lex Romana Visigothorum (506), the Lex Romana Curiensis and the Lex Romana Burgundionum.
