Well, having just spent a good part of the day flight testing a very nice twin with one engine shut down and feathered, I'm thinking the extra engine would be far superior!
As a matter of fact, I cannot imagine myself ever wanting a BRS on an aircraft I am to fly, as long as I am able to mitigate the associated safety factors!
I can imagine some non pilot "spouses" liking the BRS idea, and if that is the go/no go factor that keeps a couple flying happily together, then I do see the value in that if they do.... but not for me....
