Indeed, a USB MCU is my preferred GPIO these days. It makes my peripherals platform independent, and I can do my code development at my comfy desktop workstation with its big displays.

I find it easier to write real-time code on the MCU.

In fact, I've disciplined myself to make all of my projects -- hardware and software -- capable of running on any modern platform. It turns out that's not hard to do.
