The Acorn Archimedes was never serious competition for Commodore in that space.

I remember - as an Amiga user - cheekily pitching software upgrades to Acorn to help address the massive shortcomings we saw in RiscOS compared to AmigaOS. Even ca. 1996, a couple of years after Commodore's device, we were still smug about how much better we saw the Amiga as being.

We were willing to accept the hardware wasn't bad, but the Amiga userbase never really considered the Archimedes in the same ballpark as an overall system.
