I do not need to 'use' the stems in any further form; I only use Song Master Pro to hear them isolated when there is some question while I transcribe a song.

I cannot speak about all those other programs you listed, but I thought they all use the Spleeter technology, so I would be surprised if they produce markedly different results. That's just a guess, however.
