Among Cirrus pilots there was a telling fatal in Florida where the pilot was known to be dismissive of BRS. He had an engine failure and decided to do an off field landing on what looked like good ground. Small wheels, 3400 max gross and a 59 knot stall speed led to a poor outcome. He and his wife died. There was another in the Florida Keys that had a better outcome without using BRS so it is just an odds thing.
I know not representative but those odds are 50/50, I am sure there are Cirrus forced landing's that are successful that we never get to here about, we always here about the botched ones.
