Higher? Lower?

No doubt there is, but where exactly is the question, and the answer
probably varies depending on the scope of the project. But, just for
the sake of argument, you could compare between the STM32G0B1KET6N
(listed on Mouser for $2.95/unit at scale) and the M0G3505QRHBRQ1 ($1.44
at the same breakpoint) - both ARM Cortex M0+ with a handful of misc.
functionality, but the one has 512 KB Flash/144 KB RAM, and the other
only 32 KB/16 KB. $1.50 or so is pretty trivial to you & me, sure - but
times however many thousands/millions of units in a commercial context,
it adds up to a considerably bigger deal.
