Nerves (or Erlang’s VM BEAM) is nowhere near small enough to run on ESP32. I think a comparison is not very useful.

If you have an ESP32 you need something like Toit, if you have a Raspberry Pi you might as well run embedded Linux (with Nerves on top).

I agree, but I saw the defense that Toit wasn't just for ESP32. I have been playing with ESP chips since first tinkering with them over 8 years ago. C is fine when you're that small, Lua or even ulisp [1], forth, etc. Why Toit? Bowery Farming uses Elixir Nerves for their network of small interconnected devices to run their vertical, indoor farming operations, and I think others are looking to shrink it.
