I recently attended a TLM - a Missa Cantada - celebrating Corpus Christie.  The Church was full - what stood out for me was the fact that so many there were under 30 -- and they were attending Mass -- no business with iPhones or tablets - they were there to pray and worship.  When I attend the NO, I do not see this.  There are not many young people attending and the phones going off again and again say much about the level of mindfulness those attending this Mass bring to their worship.  For myself it is the TLM (and the music) that brought me back to the Church and the Sacraments.  It might not be entirely accidental that so little decent music has been composed for the NO.  Personally, I prefer attending NO Masses with no music or hymns at all.  If the Extraordinary Form is drawing people to the Mass, I believe it is the duty of the clergy to make this beautiful and sacred rite available.
