While Apple did have an issue with some MacBook Pro’s with the upgrade failing. I have not heard of any issues with the iMac’s [|MacBook Bricked By Big Sur? Here’s How To Fix It]. The issue is with the I/O board in these systems.

So… I would visit an Apple Store to see what they say with both systems in hand. They should be able to address the issue if it was a Big Sure defect.
