The advantage of Bloch model over Sommerfeld model

Firstly, the Bloch model can explain the existance of the insulators. Secondly, the sign of the Hall effect can be given by the Bloch model. The Sommerfeld model cannot explain these, however, many of the problems of Sommerfeld model can be solved by taking the interaction of the electrons with the periodic potential.

    I remember in the first lecture we have been given ,the lecturer said that all three models ignore interaction between electrons .I think in Bloch model takes into account interaction between electrons with ions.am i right?

    the periodic potential is provided by the ion cores.
