No more than any other cable.

So far it’s a mess.

I still have Micro USB devices, so I need two cables or USB-C→Micro USB adapter.

I have PCs without USB-C ports, so another adapter needed USB-C → USB-A.

But, I can now “dock” my new-ish laptop with only one USB-C ↔ USB-C cable to a monitor.
Monitor gives power.

Not at all a game changer, for me.

I mean, it’s just another and one more type of cable. Sure, in theory it’s simpler than many various cables and it’s even less stupid than the previous USB types, but it’s still a mess.

At least, for non-geek me, those cables are a mess as I need to be able to distinguish between the exact same cable to find which one is USB-C or Thunderbolt, between the various versions of USB-C itself, and then between USB-C that comes with or without power delivery, and with what power limitation? And then, despite USB-C supposedly being a standard there are still too many cables that just won’t work with certain devices because reasons.

Add to that the many USB-C docks (and dongles) that work… more or less reliably and more or less as marketed (even more so under Linux, but those issues exist under Mac and under Windows as well).

Older cables and ports were cumbersome, and thick and whatever but, as far as I’m concerned, for the most part they just worked like they were supposed to. And I never had an issue knowing which cable to plug into which port as they all looked, you know, different.

Nowadays, I have to label each one of my USB-C cable with some masking tape so I can identify it in a glimpse without wasting my time trying them all one by one.

Edit: some clarifications.

Not much. There was USB 3.0 even before the USB-C, so bandwidth-wise it’s hasn’t been a game changer. Over the years I’ve used a bunch of phones and other devices with Micro USB Type B and I’ve had one or two cables fail, but not at the connector. In fact the mouse I’m still using has Micro USB for charging and it’s been fine.

Edit: I’m not saying it’s not good; it is, but I consider it an incremental improvement, not a game changer. A game changer for me would be a standardised interface with a magnetic connector for example.

A little disappointing.

I had been pretty well consolidated to just lightning cables for everything. It did what I needed, the connector is small, reversible, easy to use, and it fit most electronics for my family of four. I had built up a nice stable of accessories like power banks and charging blocks that fit everything and hadn’t needed to buy anything new in years.

The switch to USB-C came with great fanfare and seemed like a good idea. However it really doesn’t give me any direct benefits and I have to buy all new accessories. Now I’m in a transition mode for a few years where I need usb-c, usb-a, and lightning cables and chargers. Worst of all the market that I kept being told was leaving behind still has more support for usb-a - my laptop has mostly usb-a, even new model motherboards for building my kids gaming computers are mostly usb-a, I don’t see a good selection of usb-c chargers, power banks are still mostly usb-a, keyboards and mice are usb-a, kvms are usb-a, etc

Trying to switch to usb-c has meant more cable types rather than fewer. It has meant buying duplicate chargers and it has meant less convenience where usb-c is not really mainstream yet. Hopefully the market will more fully adopt usb-c quickly but I meant to be a late adopter to this transition and feel almost like an early adopter
