Reactor or Dynamics?

I just made sample collision test with gravity in 3ds Max
for comparative analysis between the Reactor and old built-in Dynamics utility.

Dynamics simulation return mostly correct result then Reactor,
especially if you work with a few objects, but require more time to setup
and require enormous amount of time for calculations. Score at least worth.

Reactor has a simple settings for easy setup but the final result is
physics inaccurate. As you can see on the video, after coins hit ground
they freeze slightly above in the air in random rotation position.

Sad conclusion, at least for me, is that the Reactor does not solve
our problems when we need a realistic simulation.
