I just love the fact I can now charge my laptop and my phone using the same charger - and both charge super fast. I travel often and going with one charger is a life saver. Being able to charge my laptop from my old power bank to get two more hours is also super cool.
I remember discovering that some of my Micro-USB cables could only charge and couldn't transmit any data. I honestly don't understand why people talk about the issues with USB-C as if it was a new thing. Seems to me like most of the problems are theoretic and that most end-users are actually happy with the new standard.
