I've experienced simulated power failures and simulated rope breaks just after I'm flying but the tow plane isn't.

The rope breaks were a piece of cake, as the bang alerts you that something just went wrong and you instantly transition to landing mode.

The simulated tow plane power failure was not a piece of cake. It took a few seconds to figure out that something was wrong, find the release and transition to landing mode.

I think simulated tow plane power failure is definitely something you should see at least once (with an instructor in the back seat to keep you safe, of course)! You'll never forget it, and recognition will come faster if you ever have to deal with it in real life.
