TBH the rpi pico (rp2040 dev board) is hard to beat for the price of 5$. Dual core ARM cortex-m0+ at 100 something MHz and loads of ram and flash.

Dont forget programmable io ports with their independent tiny cores.

Oh yes, the PIO is very cool and somewhat unique. The list of examples of things that can be implemented with such a tiny "computer" (9 instructions assembly language, program size maximum of 32 instructions) is quite impressive:

In fact, the rp2040 examples and SDK docs are very, very good compared to most traditional manufacturer's documentation and by itself makes it a very good value proposition for hobbyists.
