Despite traditions to the contrary, there simply cannot be true jnana without true bhakti, there cannot be the ultimate understanding without the ultimate surrender.  Certain personalities will try to avoid one or the other under the guise of some higher wisdom, but always at the cost of wholeness.

There is a tradition that jnana is the higher path because the bhakta relies on a belief in someone or something to be devoted to, whereas the jnani knows there are neither. But true bhakti knows no object; and the true jnani knows nothing.
