Okay, as someone who has used the ESP32 before (but not the STM32), I'm genuinely curious as to why you're stating this as an assertion. What exactly is it about the ESP32 that makes it unfriendly or difficult?

(FWIW, all my ESP32 development has been in C with FreeRTOS. I'm not one of those people who insists on shoving the Arduino stack onto everything.)

I’m not an Arduino fan either but I primarily work on the opposite end of the spectrum working with the bare metal directly. ESP32’s documentation is nonexistent compared to STM32 and the ARM Cortex core in the STM32 chips has infinitely better tooling than anything with an Xtensa (this more than anything else was the deciding factor in my book).
