Basically more everything. 2x Cortex M33 cores with floating point, 520KB ram, more PIOs, bunch of secure boot stuff (I have mixed feelings about this), and can boot to a mode with risc-v cores instead of the M33s.

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.
