I like flying twins, I have several hundred our in various types from the venerable Seneca to the Navajo and Otter.
But for private flying these days the costs just do not stack up. I fly a Mirage now, 17gph for a 25,000ft cruise at 220kts and fully certified for known ice. A twin just does not come close. But the Mirage is a long trips aircraft so I keep my Cessna for the fun touring and still single engine costs.
I don't believe that twins are any safer statistically, just that they give some people a better feeling of safety!
