A plane with poor glide is easier to spot land, but a plane that glides further can give you more options and (in my opinion) is safer. But that alone isn’t what makes the plane safer. If you lost oil pressure, or the governor on takeoff, and your low pitch stops aren’t preset correctly, the rpm will go to 3000+ and you will have less thrust because a flat blade isn’t biting the air. Correctly set low pitch stops are like having a backup that will maintain control and some bite on the air, like a fixed pitch prop set for climb. That’s what makes the plane safer. I know someone who lost his governor on takeoff, and the plane fell on its face, no thrust, 3300 rpm. He throttled back and got it stopped on the remaining runway, melting out his caliper o-rings in the process.
