I'm an Amiga diehard from the start but the industry caught up in a lot less than 10 years. Also, the amazing X68000 was a thing in Japan as of 1987.
If I'm paying double the price, of course I'd expect better performance, but Amigas gave great value for money between the mid 80s and early 90s.
The X68000 was basically arcade-class hardware in a PC form factor, with a price to match. There are reasons why Capcom used X68000s as their dev machines for CPS1 games.
