As far as I know, these don't have programmable IOs (PIO), though, which may make it more difficult if you want fine timing control of your GPIO, such as "bit-banging" (not really with PIO) arbitrary protocols. And they have much lower power consumption.
Fair point though, the price difference isn't much, an the Pi Zero are much more capable.
