I have a glock and they are great guns. Very accurate. But like to carry the sig 365XL. I like the manual safety. Some don’t like manual safeties.
I lean toward the axiom that the real safety is person handling the weapon. Then again, accidents happen and if the safety makes someone more comfortable carrying, go with what works.
Remembering to disengage the safety on the range is easy. But wait until you're in a high stress situation and go straight to pulling the trigger and nothing happens. I saw a video of just that. Bad guy tries to rob store owner and store owner forgets to disengage safety. Fortunately for him, the robber was a bad shot and the victim eventually remembers to disengage the safety and returns fire. For that reason I'll never carry a firearm with a manual safety. I can count on my Glock to go bang when I pull the trigger.
