Nama chanting will ultimately take you to the same goal that Vedanta vichhara or Yoga or 'Karmanushtana' takes one to.
Through Nama one can attain the highest state.
The Azhwars, the Nayanmars, Thiagaraja Swami, Panduranga Bhaktas, Chaitanya Mahaprabhu have all shown that one CAN attain liberation through mere chanting of Nama.
Even today we find Sadhus who have attained the highest state through mere chanting of Nãma.
This is the glory of 'Nama Sankirtana' -- An absolutely easy, simple path.
