I'd like to add that from the perspective of the EU, and I'd say also from the perspective of most citizens, it is irrelevant which charger standard is better.

In the bigger picture, it is much more important that there be only one type of charger, standardized in form and function.

Sometimes, being less of a hassle counterbalances technical shortcomings.

If the average EU citizen is anything like me, somewhere in their living space you can find two bins: One for an assortment of non-interchangable (and in part obsolete) chargers and one for broken headphones.
