For what it's worth, the higher end of pro audio interfaces have been using type-C connectors for many years due to those connectors also being used for Thunderbolt-3. Personally, I like these connectors better than the Thunderbolt-2 Display Port or the USB Type-B connectors.
What I really don't like about Type-C is that lack of standards on cables. Also, the lack of markings on the Host and Device ports that state their capabilities.
Believe some folks were talking about USB connector reliability simply in virtue of older Type-B connectors being more girthy, and more solid in virtue of the dimensions and contact surface interface quantity + thickness.
There is good reason also to assume wear-characteristics are more prone to sooner issues with connectivity (in the same manner every single one of my iPhones I've used, eventually have their connectors slowly start to lose the initial wonderful tolerance). Though iPhones don't use USB-C obviously.
I haven't look at the dimensions comparisons and things of that nature with surface contact with properly made USB-C interfacings. There seems to be an extreme variability on the market (for instance my Android phone's interfacing with it's stock cable is complete and utter dogshit, it's even somewhat wiggly, compared to my Macbook who's USB-C charging cable interfaces very sturdy and satisfyingly smooth with both the Macbook itself, as well as the USB-C terminated power-brick).
I feel as though most Type-B connectors from experience, have had FAR less variance with tolerances in all the devices used (mostly printers from my experience, and a few DACs obviously).
But if anyone is questioning the long term viability of USB-C in terms of wear cycles before it starts losing reliable connectivity, of that I have no idea compared to USB Type-B. Add on another list of things makers of these standards should demand from cable manufacturers and end-point interface suppliers. To me it just seems most people aren't getting the common solid physical satisfying connection with USB Type-B, instead they have to live with sometimes somewhat loose, or sometimes far too tight cable connections, so the wonder is how long would that hold up in use cases where swaps might be a daily occurrence or something.
EDIT: What I mean to conclude on is, if you rub up against the connector, or have some force applied against a cable connected to a USB-C connetor -- I'd place my bets that would snap off, sooner than a USB Type-B connection.
