One hears quite often of people who go to the Extraordinary Form because it is difficult or in some places impossible to find an Ordinary Form Mass offered with the same solemnity and reverence and awe and joy as even a mediocre EF Mass.  It's not to escape the Mass of Paul VI per se, but rather to get away from the Mass of Eugene Walsh and Rembert Weakland (etc.)

After Summorum Pontificum, Extraordinary Form congregations also have many more protections than Ordinary Form congregations.  A good Ordinary Form which takes a congregation years to build up can be ruined in weeks by a new pastor who is ideologically opposed.  But EF congregations have clear recourse to their bishop and to Rome.
