Good, though in practice it's not the charger the problem, I use the same USB plug everywhere, it's Apple and their cable. Right now I always need with me a micro USB cable, an USB-C one, and Lightning, because Apple thinks different™. What's Apple reasoning for not abandoning Lightning for USB-C on their phones?
I don't know about other technical aspects but I really like the fact that Lightning male is just a solid block. It's definitely more durable than type-C
