I do! as I said the pico/esp32/rp2040 are useful tools to have lying around. I'm currently using one to be a stepper controller for a project I'm doing now.

However the best thing about the Rpi GPIO stack is the support. If I google "how do I do x with y on pi" I will get lots of resources, along with the official docs (the rp2040 docs are great by the way) and a bunch of hardware that is mostly plug and play.

Yeah, fair; there's something nice about the fact that the Raspberry Pi is "just Linux"; it's not some attempt at an embedded version of POSIX.

You have the full Linux kernel and packages to play with, the GPIO stuff (if performance isn't a huge deal) can easily be controlled by simply writing to files, meaning that you can do quasi-embedded stuff in basically any language you want, or at least any language that has an ARM port to Linux, which is basically everything nowadays.

Still, I'm quite partial to the ESP32 with NodeMCU just because the power consumption is so ridiculously low and NodeMCU + Lua is pretty easy since it has full GC and gives you a node.js-style callbacks that I think are generally easier to work with than doing it myself in C. Most of my embedded projects have moved to the ESP32 as a result.
