Difference between the Photon Transform View component and the OnPhotonSerializeView method?

Hello,

I am quite new to photon PUN so sorry if this question sounds redundant!

I wanted to know if there is any difference in the way data is sent between using the Photon Transform View component on a gameobject and implementing the OnPhotonSerializeView method in a script on that gameobject to send the position.

For instance if I was to use the Photon Transform View to send the position of the player would it be any different from doing this?:

#region IPunObservable implementation

        public void OnPhotonSerializeView(PhotonStream stream, PhotonMessageInfo info)
        {
            if (stream.IsWriting)
            {
                // We own this player: send the others our data
                stream.SendNext(gameobject.transform.position);
                
            }
            else
            {
                // Network player, receive data
               gameobject.transform.position = (Vector3)stream.ReceiveNext();
            }
        }

#endregion

Any difference in terms of performance and bandiwth limitation over the photon cloud server? Is one aproach 'right' and the other 'wrong' for some reason?
