The '020 was earlier than the 80386 and the '030 better. But yes, by the time of the 80486 and m68040, Motorola was better, but quite late, plus Motorola never had the impetus to bring it to higher clocks, whereas the 80486 got to 100 MHz.
It's certainly not correct to say that the m68060 "pretty much never shipped at all". I have several m68060 systems that would disagree with you. The chip even went through six revisions, with the last two often overclocked to 200% of its official speed. It actually competed well with the Pentium on integer and mixed code, although the Pentium's FPU was faster. Considering the popularity of m68k and x86 at the time, that was pretty darned impressive.
The m68060 is in countless Amiga accelerators, including ones made in the last few years such as Terrible Fire accelerators. Personally, I have a phase5 Cyberstorm MK III and Blizzard 1260. There were Atari '060 accelerators, a Sinclair QL motherboard that has the option of taking an '060, they were a native option in Amiga 4000 Towers, in DraCo computers / video processors, and in VME boards.
I'd love to get one of these to help do more m68k NetBSD pkgsrc package building:
