Default Threshold 800A and other old models: Mospec 2N5876/2N5878 or ON MJ21193/MJ21194 ?

I discover the follow websites from Mospec:
POWER TRANSISTORS
CONTACT US
and I note, that there offer the most old Motorola BjT power devices.
So I must ask, what is the better solution for replace:
to choice the Mospec with original type number or the ON successors from Motorola?
Because I haven't the possibility of analyzing the P-spice parameter, I can't find clearly the right answer

It has been my experience that many times those semiconductor places require minimum orders of devices. I don't know this place but I buy high power obsolete MOSFETS used for xenon switching power supplies from one place in China and I have to buy at least 24 pieces each time.

A curve tracer about
DIY Curve Tracer for PC
and a additional CAD supported P-Spice analysing certainly would be find out this

In this case the last posts of
bipolar (bjt) transistor families for audio power output stages
could be of interest

It looks like the On Semi parts will drop right in, and they
have more current and dissipation. I would go for them.
