Watch the video and then argue it out in the forum. 
I think it was in some ways, in particular the 32-bit ARM CPU was far more advanced and waaay faster than the 16-bit 68K one in the Amiga. It had more colours and better sound, but no dedicated graphics blitter chip which significantly held it back. Oh and there was much better ecosystem support for the Amiga too, which is critical for success. I'd call it a tie, depending on what you wanted out of it.
