Supercharge or Turbocharge?

Jordo!

There's really no reason to think that.

I suppose you could make the case that there are fewer parts that could fail on a SC set up as compared to a twin turbo (for one thing, only one turbine to worry about), but there really is no reason to presume greater safety.

Centrifugal blowers do tend to make power a bit later in the rev range than a properly set up twin turbo (although the torque curve looked pretty flat for this motor on that set-up), but under high load approaching redline, both are capable of destroying a motor in short order if the tune is bad or if the internals cannot tolerate the extra power.
