 Almost all of the consoles use RGB Scart, but I only see ghosting/blurring issues with some of them. The main ones that need solving (because the fuzziness is so distracting) are:

 On the Saturn, interlaced modes hide the blurring/ghosting quite well, but that's down to the fact that the two fields are being overlaid on top of each other, cancelling out some of the ghosting of the previous field. My monitor (Dell U2410) does a decent job of deinterlacing the signal, so the OSSC is set to pass-through for 625i mode. In the above images all scanlines and post-processing is disabled.
-Using the same scart cable as before, changing the routing had a dramatic effect on the quality of the image - the new run is clearly pixel perfect and shows no sign of a ghost image or blurring. This obviously means that it isn't the console, scart cable, scart switch or OSSC at fault.

This obviously means that it isn't the console, scart cable, scart switch or OSSC at fault, but could be either the under desk route it takes or the longer extension it uses when connected that way.
 //Now if I can only find some way of determining what exactly is interfering with the signal when it runs in the cable basket.....//

 Since changing the extension cable that the Saturn connects to made no appreciable difference, the only thing left to do with that system now (other than move it to be far closer to the monitor - which, without re-arranging all of the other nearby systems, isn't an option) is to try an upgraded Saturn scart cable.

+Well the [[https://www.retrogamingcables.co.uk/sega/saturn/SEGA-SATURN-RGB-SCART-PACKAPUNCH-PRO-CABLE|RetrogamingCables.com cable]] arrived, and it certainly made a difference - all of the images below are with that cable and the original long scart extension:

+The image clarity is now equally as good with the scart cable and extension as it was with just the original scart cable connected directly to the gscartsw, so that's really good news.
+But...
+=== White Balance Issues ===
+However, this new cable has introduced a new problem; the white balance. More specifically the white balance sometimes shifts from bright white to slightly pink tinged. If you blink you can miss it, but it's cleared to see when you have an all-white image next to the same screen that is pink-tinged:

+//I really hope that it's just a loose connection somewhere along the chain, because to now have a pixel perfect image only to have everything tinged with pink every few seconds is just the icing on the cake!!!//
+**[Update: July 2020]** //Yep//, turns out that the new cable is a //much// tighter fit into the Saturn video-out port than the original, and it just wasn't pushed all the way in. Picture is now perfect, well, as much as an analogue RGB signal can be.
