I don't know how people can think the RGB version of these two pictures looks 'better'. Certainly you can see the pixels and it is less blurry.
But look at those two pictures. The composite one looks like a painting to me. It looks beautiful for a video game! That dark plant stock in the foreground on the right really give the picture depth. Gorgeous!
The RGB version looks nothing like a painting, but a just a lo-res pixely graphic. The whole thing just looks flat and you get none of the depth you do in the composite one. What I see in RGB is lo-res and clunky, and a 'not real' feeling. I know this all subjective, but I'd rather play the top one.
I remember when I got an RGB monitor for my Amiga 1000. I had been using a TV for a long time. I mostly played games on it and Flight Simulator was almost unplayable on the TV because I couldn't read what the text was for all the airplane controls. I got that RGB monitor and the text looked AWESOME in RGB, crystal clear and I finally could really play flight sim. All my other games however sort of lost their charm/beauty. They looked so bad in RGB. For a long time I left the TV hooked up for games and used the RGB monitor for regular computer stuff.
I did some pics of this with the Sega saturn too.
