Embassy is next-level in terms of developer experience.
If you must use C, ESP-IDF/Arduino aren't terrible. But you still don't really have a package manager or means to abstract anything, especially across devices.
The cohesion present in Embassy between the HALs, probe-rs, etc. is really amazing.
With Embassy for example, I can run the same async/interrupt-driven I2C driver code on any number of different MCUs across various manufacturers. This holds true for many, many different types of peripherals in the ecosystem. For the unique peripherals, implementation style and interface are extremely consistent and high-quality.
