Default Replacrment of ZTX 550 and ZTX 450

Hi! I'm have some difficulty finding ZTX 550 and ZTX 450. I saw someone used ZTX 551 and ZTX 451 and some used BC 550 and BC 560. Are they good? Which one is better compare to ZTX 550 and ZTX 450.

Thank You.

It would help if you tell what you will be using them for Since this is the Pass department I guess its CCS's and so on for Aleph's or Zen's?? Any decent BJT with ratings to suit, will be good enough. MPSA18 and the BC's you mentioned are often used.
