The Edison screw works quite badly for LED bulbs commonly used today. The electronics are all buried in the base part, which has very limited cooling, so they get extra hot and kills the lightbulbs prematurely when the LEDs themselves last much longer. It is also not standardized w.r.t. voltages, power limits, etc, making it prone to user error.
The European and British plugs both have noticeable advantages compared to the American one, in that it is much harder to get shocked by them or cause arcing. Also, a universal plug would be much more helpful in a world with the same electric power systems everywhere, which is not the case.
Though, it isn't the screw connector that makes led bulbs a bad fit. It is the AC power delivery. And, yes, hvdc is likely better, but only in recent times with modern equipment. And even then, probably more debatable than makes sense.
