This discussion is sounding like one of those pointless arguments in a pub about whose footaball team is best.
Irrespective of the reliability of modern turbine engines, the point about twin engined aircraft is that they have other duplicated systems, such as those which are required for flight in IFR e.g. generators, SAS/autopilot systems, hydraulics etc.
This rules out singles where continued flight is a safety and legal requirement. There is certainly no compelling evidence that a single engine is more reliable and therefore safer than two.
Having flown both singles and twins, I've always said that I'd rather have a well equipped, powerful single than an underpowered twin, some of which I've also flown.
But the latter came from "the dark ages" and modern twins do not generally fit into that category.
I'd say that both singles and twins each have their own "niche" and both will always exist. It's totally pointless trying to argue that singles should be exclusively manufactured and used because of a personal preference.
