USB-C is mostly a mess if you try to get away using the cheapest adapters/cables you can find, that often times won't follow the spec. Most of the issues vanish if you use high-end cables/adapters from reputable manufacturers. This is a departure from the world of Micro USB where
most cheap cables worked just as good as "high end" cables.
There are caveats. For example, my Nintendo Switch, a major electronics device from a major company, doesn't fully comply with the full USB-C PD spec. As a result, you can't assume any power adapter will work.
It's these caveats that are the real downfall... for those of us in the technology world, it's easy for us to be aware of them. For everyone else, it's not. There's also the whole Thunderbolt 3 & 4 using USB-C thing. I do feel bad for non-technology people trying to wrap their heads around this one.
In general, I've had good luck with USB-C. I can power my laptop and display to a 4K monitor with a single cable. It's awesome. I've also had plenty of frustrating experiences and weird USB bugs with certain hardware combinations.
Despite some of the issues, I think it's still a net positive.
