Hi, how are you? Well, about the title, which microcontroller do you prefer to use and in what situation do you use it? The question comes from the fact that I am buying some microcontrollers to use throughout my university career, specifically I bought an Arduino nano, a Raspberry Pi Pico , a STM32F103C8T6 and an ESP32, I would like to know your opinion about these and about any other that may be useful to me
