I completely switched to the Adafruit Feather M4 series for my hobby electronics about 5 years ago. Each board might be a little more expensive than a base Arduino, but they are way more powerful and have a lot of great features.

If you want to go "budget", STM32 hardware (like the common "blue pill" STM32F103C8 board) is priced comparably to a knockoff Arduino, if not cheaper.

  You can now get much more powerfull STM32F411CEU6 boards for the same price.

    Which boards are you thinking of? "Blue pill" STM32F103C8 boards are $2 to $3, if you're willing to run the risk of getting a cloned microcontroller. (The clones are actually quite usable for most purposes.)

      The clones even tend to have more memory. But I was thinking of those boards: https://aliexpress.com/item/4000103610226.html https://aliexpress.com/item/4000103610226.html (also supported by RIOT btw https://github.com/RIOT-OS/RIOT/pull/12778 https://github.com/RIOT-OS/RIOT/pull/12778)

        Oh, those! I have one of the F401 models -- I didn't know there was a F411 variant, though, nor that they've gotten so cheap. There might be a purchase in my future. :)

        Some clones even have chip errata fixed.

Those M4's are handy! I use the Adafruit Itsy M4s. Wait does this support them?!

For a similar reason I switched over the Wemos Mini-D1. In my case having onboard Wifi is usually more important to me than having extra I/O ports.
