As already stated, there is no best. Most of the speakers mentioned have many positives and a few negatives. I will say that hearing the Horning speakers with the one watt 45 tube amp we built was an eye opening experience. I have heard them before with other amplification, but they never sounded like this. One pure watt of power made those speakers sing. Mid-range magic and so natural.
But overall I would say that field coil speakers will outperform most of what is mentioned here.
Happy Listening.
