What is the best Amiga in your Opinion?

Why, the Mil-Spec (tm) Amiga 2000, of course.

Seriously, I'm not certain I can name a favorite.  I have one of each of the desktop models (no towers and no special editions,) and each one has been great for its particular purposes.  My 4000D is my main machine, but a favorite? Can't really say.  I love all my children equally

It's easy to forget how costly an '040 was back in 1993. However I do agree that both the A1200 and especially the CD32 should have come with fast RAM by default, and the A1200 should have been configurable out of the box with 4MB and 6MB options (an easy upsell from the base price). A 20MHz '020 would have made a difference, but I guess the CPU selected was restricted by Motorola's pricing at the time.

Mind that this was also during a time when the competition was paying a tonne of money on custom-designed consoles with not-so-inexpensive processors: the Sony PlayStation, the Nintendo 64, and the ill-fated Sega Saturn.  While everyone was clamoring for more powerful consoles, the Sega Genesis still held quite a field four years after release with its 68000 processor and Z80 co-processor.  As well, the NeoGeo was still a powerful game machine with the same processor specs as the Genesis.  The CD32 could have been much more than it was when released, IMO.

It amuses me that Atari was approached by both Nintendo and Sega to market their consoles and Atari couldn't agree with either.  Whoops!

To be fair.
CD32 - September 1993
Saturn - November 22, 1994
Playstation - 1994 (Japan)
Jaguar - November 23, 1993

True.  I know this doesn't reference my post, but I do want to point out that while those machines were released later than the CD32, the development occurred during the same time-period.  For instance, what we know now as the Sony PlayStation actually started development around late-1992, with four years of prior concept and joint development with Nintendo.

The best Amiga to me is still the A1000.  The original.  It was a huge jump.
All of the others are incremental updates, and too slow and not enough for the time at that.  Doesn't mean they weren't great.  I love my A1200.  
But I gotta go with the 1000..

Yeah, I could see this.  The 1000 was definitely a giant leap forward in home computing (arguable against the Mac-heads.)  I would also say that the 500 and 2000 were also fairly good leaps forward: the 500 solidified the Amiga concept and the 2000 gave the Amiga a PC-worldly affect.
