I've used more usb gadgets than most people, as I deal with electronics a lot, but I never had a single problem with micro usb. Not sure why people hate it so much.
Well I'm not sure it takes an expert to master a plug.
But I'd understand the hate if it was universal (pun maybe intended), but everyone that hates micro-usb seems to adore usb-c, while I feel like it's potentially much more fragile. When handling usb-c I always use a lot more delicate care than I ever did with micro-usb. Mostly because even though I'm pretty good at soldering very tiny things, I'm not confident I could replace most usb-c receptacles without messing it up.
Usb-C is way more robust. It's thicker, stronger, goes in both ways, has no moving parts. Micro USB is thin, flimsy, has stupid spring tabs that weaken pretty quickly and result in a cord that just falls out of your device when you pick it up while it's plugged in. Fuck micro USB.
