Despite what the article says, the 68000 was microcoded too. Another difference is that the 68K was a 32b architecture, not 16b, and that required investing more transistors for the register file and datapath.

"Oddball string instructions", as an assembler coder bitd, they were a welcome feature as opposed to running out of registers and/or crashing the stack with a Z-80.
