The Amiga was ahead of its time in many ways, and the pre-emptive multitasking was fantastic, but claiming it was some paragon doesn't help anyone. If you wanted a fun home machine attached to a TV, it was great. Even a fun home machine attached to a monitor. If you wanted a business machine with a monitor, it wasn't the safest or best choice, if only due to a lack of software.
16 colors is still way better for games than 2 color black-and-white. The fact that the Amiga could achieve 4096 colors in a world where 16 colors was the norm, was astonishing. The resolution did not matter. The capabilities mattered, and the Amiga was far more capable in every way than the Mac. The mac had 1-channel 8-bit sound, the Amiga had 4-channel stereo 8-bit sound, and was capable of 14-bit sound. So go nitpick some more if you want to, I don't care, but I won't be responding to you anymore.
That being said I preferred the Amiga.
The Amiga was a bargain in comparison, but it was not without its flaws, like all early machines. I had an A500 with a 1084 monitor, and the flicker at high res was bothersome to me. I later upgraded to an A3000 w/VGA monitor, and it was a vast improvement. I ran at 640x400 for everything at that point.
I think you are underestimating the price of "flicker fixers" at the time. I looked up the price of a Microway flicker fixer in an old Amiga World from 1988: Over $500. You also had to add an a VGA monitor: another $400.
Still way, way better than a 2-color mac at about the same price. And it wasn't even necessary, the Amiga 1000 was amazing without it.
