1. VDC has not C64 VIC color palette - it has CGA palette, only dark yellow is replaced/adjusted to orange.
Really can be C64 pictures good, but I think better graphics can create VIC20 even with resolution limited in default modes. VIC-II is really mysterious - why designers removed interlace? why used that very wrong color selection - except greyscale? It is only VIC-II which is missing interlace, even VIC-IIe in C128 has interlace and allows 320x400/160x400 graphics / 37x50 text... and even - offers 11 new colors... Problem of C64 is in attribute clash - color cells 8x8 or 4x8 are big limits, I know that fake interlaced modes it can solve, but why I named it fake: really it has nothing with interlace. Even C128's VIC-IIe has Real Interlace... but that's to C64.
2. TED has 121 colors by default (here it needs to write why designers selected black and white separately when shading black to white offers both in 7 color greyscale, but it is Q only for me, really it is not limit).
Q is to TED HiRes 320 horizontal - I'm not sure about color cells - offers it 8x2?
VDC offers in horizontal up to 480 pixels 8x1 color cells, other modes 8x2 color cells...
Even - look here:
http://www.mirkosoft.sk/conversion/vdc256colors.png
VDC in 256 colors, really 136 (for color duplicates) in 640x512 pixels 8x2 cells interlace.
Here it needs only to say - yes color combinations of 16 color palette vs of 121 color palette... (but of course duplicate colors need to fix count).
In case of VDC I'm confused when you writing about RAM. Designers of Commodore 900 used MOS 8563 chip too, but dedicated there 128K VRAM (don't know how was made addressing) and when was C900 project cancelled MOS 8563 was used in C128 - with limited RAM 64K, even unexpanded 16K. What offers 128K? 1024x800 pixels monochrome graphic mode - but this needs more RAM than 64K, so limit is VRAM - why they did it, really don't understand. But it means that VDC is able to display 1024 pixels horizontal resolution.
Reached was 800H and 800V on C128.
But back:
3. I try the pictures and know these pictures in past I compared it to more computers - this thread is not war between graphics - it is what we can do - no war, in my eyes is TED great chip, Plussy has perfect RAM management - I want to buy one, but of course it will never replace my C128...
I wanted to compare also VIC-I and VIC-II, maybe VIC-IIe and even maybe VIC-III (where is hard to get sources) in this thread.
We can make TED Challenge, but can we include also other Commodore 8-bits?
So, for interested here are tools, I will expand VDC Renderer later when I find time.

Ok, this weekend I do the conversion.
Here's conversion, but first notes:
1. parrot
http://www.mirkosoft.sk/conversion/parrot.png
I know main goal is to compare single color - TED has 121 single colors and VDC 16 colors, but no matter - here needs to say, only replaced.
2. Amiga picture
I think result is visible - VDC has no problem with colors like TED, but both are not enough to compare with Amiga - there are colors which is not possible to replace - except blue sky (I replaced and each of you can do the similar with with TED picture) - but TED generally failed in toolbar - resolution makes it impossible to see anything, VDC is much more better - in this picture are results so comparable that TED has big disadvantage - resolution.
