dithering question

Hi!

I have been just looking at recently released MULTI graphics, and what I noticed is that the majority of images use horizontal line dithering. For example:
Always Look at the Bright Side of Life

While in the past most images used checkerboard dithering, for example Hein's graphics in Dutch Breeze. But current example:
Birdman

(Note both images contain both type of dithering, just one is much more dominant.)

And very few use diffuse (random) dithering for some reason.

So what is the reason of this difference? Is it only the preference of the artist, or is there an advantage of horizontal line dithering on a TV? I do not have a real C64 anymore, so I cannot check it unfortunately.

Another question: why are there so few diffuse dithering out there? Is this because this is much harder to do, or is there some visible disadvantage?

Thanks

After paying a ridiculous amount of money to buy it, then driving 16 hours to fetch it, I am a proud owner of an original Commodore 1802 monitor.

Still no even/odd lines, LOL:

I will borrow another C64 and will test with that, maybe I have a special unit, who knows?
