Apart from the primary consideration that must be made, i.e. any tube's potential to synergize with your other components, speakers, room acoustics, etc, assuming you want a neutal tube, ala the Telefunken, which I consider one of the best, you might consider the not so old NOS EI12ax7a which was made with the Telefunken machinery which was purchased by EI. I just saw someone selling an unused octet of these tubes (labeled ARC) for slightly under $200. A deal(!) if you can justify getting the octet. If you are interested in the Tele's you might do some research first. I haven't heard the other tubes you mentioned so I can't compare.
Buy 12ax7 tube
