You do realise that there are two architecture xtensa & RISC v. RISC v isn't as power efficient.

The xtensa super low power mode can deep sleep, wake on timer or external interrupt, and (based on duty cycle) probably run for year or more on a 9v battery.

Micropython is similar in performance to Arduino on esp32. Poor Async, around 10x slower than rust and much harder to do Async, etc. Possibly better for beginners, but even that won't be true in another year thanks to projects like embassy-rs

Rust and C have similar compiled performance. The difference is rust Dev on esp32 is easier to target with other architectures, also rust will probably be a bit easier to detect & debug any crashes during design making it a lower cost to develop than C equivalent (because C is more permissive, it's easier to make accident mistakes)
