Raspberry Pi and Raspberry Pico are entirely different and unrelated devices.
I've been using the original Pico and also the Pico-W (with WiFi for one more dollar)
for a bunch of projects; they work well and the price is hard to beat. The PIO
(programmable state machine) subsystem is particularly impressive; for example, I used it
to implement a DDCMP sync line interface.

As for the RP2040 being cheap crap, I beg to
differ with you. It is a solid chip, produced in 10s of millions at least. And, I would
bet, a better quality chip than your Z-80, if due only to improved IC manufacturing
technologies.
The pi looks like parts were picked for lowest cost,biggest profit,
like most products today. RISC chips have been around for 40 years, and yet versions
change like hotcakes every year.
