Are all the tubes nos or used stock. Many times with the older tubes people will list them as nos when in actuality they may have some usage. Not that this is a problem as most of my tubes are slightly used vintage tubes and I rarely have any issues with them. You can also save quite a bit of money buying slightly used vintage tubes that test well because they seem to last forever. Most of what you listed, with the exception of a couple, appear to be vintage and they should all perform well and last you for many years.

As far as what's best, only you can say what you think sounds the best. I really like the Brimar, Amperex and Sylvania tubes in my Marshalls. Be careful though because many tubes were rebranded by the manufacturers back in the day. It may say RCA on the tube when it was actually made by another manufacturer.
