I see the problem to get reliable benchmarks for such old hardware, but The ones given in the BYTE article are just nonsense for your comparision, they measure BASIC and disk/file access between three very different operating systems and basic interpreters - so almost zero meaning for determining CPU performance.

Yep, and Hitachi in Japan, and Rockwell, and... it's actually in the Wikipedia article:

Several other companies were second-source manufacturers of the HMOS 68000. These included Hitachi (HD68000), who shrank the feature size to 2.7 ┬Ám for their 12.5 MHz version,[4] Mostek (MK68000), Rockwell (R68000), Signetics (SCN68000), Thomson/SGS-Thomson (originally EF68000 and later TS68000), and Toshiba (TMP68000). Toshiba was also a second-source maker of the CMOS 68HC000 (TMP68HC000).
