I think trying to cut power at least once is better if it's possible. The reason is that digital is just an abstraction over analog, electrical activity. Plus there's actual analog in there doing work, too. So, seeing how all the chips in there respond to an actual and instantaneous drop of the power would be an interesting test of the models they're built against.

Like an above commenter mentioned, weird activity in electrical system can make some products go haywire and even corrupt data in unexpected ways. Of course, simulated takedowns and all appropriate measures for countering common issues should've already happened before a real one. Just to be extra clear there.
