Safety is not a device.
Safety is a mindset.
I prefer DA/SA handguns without a manual safety. Next would be DAO without a manual safety.
In fact, I think the only handgun I have with a manual safety is a Walther P22 that my wife really likes. And they designed the safety on that thing backwards.
No safety, but I only carry Glocks and don't see a need to retrain myself to carry an inferior sidearm.
