This is a most excellent place for technology news and articles.
What is the advantage of a Pico 2 compared to the ESP32 variants?
Better marketing. It’s also easier to get a build pipeline for ARM than Xtensa and RISC-V.
I would say the documentation is more thorough, and at least for the non-wireless versions, there are no mysterious code blobs. The source code to everything including the ROM boot loader is online. The Pico boards also have a nice voltage regulation system so you can run them on a wide range of supply voltages.
