Krishna consciousness is perhaps the most sublime and pure philosophy there is. It is because it is very personal. Unlike other paths where God is either faceless and formless or God is old sterile and mute, in Krishna consciousness, God is portrayed as an active Personality where all other personalities emanate. He is seen as the fountainhead of all other personalities. So one can imagine how dynamic Krishna or God should be that all types of people can see a portion of them in Krishna. This feature is the most attractive and unique to Krishna consciousness.
Just as the material counterpart, for example, when we think of any particular field of interest say cricket. What comes to mind, perhaps great players of the game such as Vivian Richards or Sachin Tendulkar etc. No one thinks about a bat, or a ball or a 22 yard cricket pitch. This is because cricket is made attractive by different personalities. They bring flair and character to the game. Otherwise what attraction is there to a round ball and a wooden bat. This is true for all fields from academics to entertainment to sports to politics. It is the person that attracts the minds and not the mundane field per se.
Similarly Krishna conscious philosophy is most attractive because of the most attractive Krishna and because of the great personalities that directly come from Krishna such as the great devotees Ramanujacharya, Madhvacharya, Narada Muni, Nanda Maharaj, Kunti Devi, Arjuna, Rupa Goswami, Prabhupada etc The scriptures are filled with stories of these great personalities that it easily attracts the minds of people and because of this attraction one naturally evokes love for God. Therefore one can say Krishna consciousness is the purest and most sublime form of religion.
