Of the three mentioned the B-58 is not a Mach 3 aircraft.
The XB-70 has a nice VC, better than some of the others Alphasim/Virtavia was releasing during that time and among those mentioned above. You can see images on the sales page I'm sure. Texture wise there were only two historically accurate options for the Valkyrie and both were included. Like the SR-71 it was not a point and zoom aircraft. It took time and a schedule of altitude steps to get her to the high speed. The Glowingheat SR-71 is still the best one out there despite having a few years on it. The flight model is spot on according to pilot(s) who actually flew it.
I was involved with the development of all three that you mentioned. If they are on sale get them.
