I’d prefer USB-C for the orientation-free plug convenience and the (hopefully) more robust connector and port.
Micro-USB has always seemed on the fragile side to me. If you’re a parent with active kids, you’ll know all about how the port-plug fit seems to get looser and looser with time and use. Compare that to Apple Lightning that fits just as firmly a year down the line as it did on day one.
I think USB-C is possibly being avoided for now due to the potential for misunderstood expectations. No one ever expects a micro-USB port to do anything but provide power (mostly) and data connectivity (sometimes). With USB-C, there’s every chance someone will buy eg: a pair of headphones, not read the label “USB-C for charging only; not for audio connection” and raise hue and cry about their being “duped” into buying a set of headphones with implied USB-C audio capability.
Same goes for eg: powerbanks where the USB-C port may be for input only, output only or both. Tech heads like present company will know to check the product label and know what they’re buying. The average consumer will just see a USB-C port and expect that if it’s a port that fits the cable, surely it must do everything!
