I thought that people routinely wrote assembly that was better than
a compiler's code on old processors like the VAX, but that a compiler
is better on a RISC (or similarly complex) architecture?

One of the local Amiga guys over here wrote an entire spreadsheet in
m68k assembler about ten years ago...
