There are so many ways things can go wrong it makes your head hurt to think about it. I see Motorola used on my reference SE/30 analog board for the Bu406 horizontal switch application. So that vendor is likely a safe initial order choice. But I think testing to see if the raster has any strange irregularities is necessary also. Sometimes modern parts can be too good (switch too fast) and cause unwanted effects. One way to go is trying the three name brand vendors line item ($1.18 qty 1) first in your initial tests. If they test ok, you are done, cost to order and test all the others exceeds savings for your limited production run. All the other lines have unknown or uncertain vendors that seem more risky even if you were lucky enough to have all the test equipment and time to run qualification testing on all kinds of stuff including collector breakdown, leakage, and switching times, checking to see if they met the spec sheet requirements.
