Statement from my previous post bolded for emphasis. The GBSC will output RGBHV by default or component with the right cable and right setting in the UI. I made note of this because Taiyaki considered outputting his GBSC to a second gscartsw; this won't work right unless the gscartsw has a sync combiner feature I've forgotten. It also accepts RGBHV on the DE-15 input but can do RGBS with the
necessary mods and a sync separator. Alternatively, you should also be able to RGBs on the appropriate pins on the five-pin header on the top of the board next to the DE-15 input. You'll still need the resistor tweak for this if I am not mistaken.

"Best" depends on your setup. For Taiyaki and myself who have multiple systems with which we want to utilize a switcher and still have native 240p/480i output, getting the SCART cable from Retro Gaming Cables or Retro Access with the 15/31 kHz switch is the ticket. If you hate Bangai-O and a couple other games, you could get an original or knockoff VGA box and output it to a GBSC which does not have the resistor mod in the link I shared above, configure it for downscaled output, add a sync combiner on the GBSC output, and have fun.
I also found a
source that mentions that RGBHV input being subject to downscaling could have issues. The author says he went with component input. As I'm sure you already know it's incredibly easy for the AV chain at the heart of your setup could become very complex rather quickly. My recommendation is to get all the consoles you want together, determine what their output options are, and find ways to standardize their expectations. For me, the current target is a very capable 480p monitor. My Twin Famicom, NES, and SuperGrafx are all composite devices. My SNES, Master System, Genesis, Saturn, and PS1 are all strictly 240p/480i SCART. My Dreamcast and PS2 are 240p/480i/480p SCART. My Xbox, Xbox 360, PSP Go, and PS3 are all 480p component for now (need to check on which of these can do proper 4:3 HDMI). My N64, Gamecube, Wii, Wii U, Switch, PS4, and Xbox One are all 480p HDMI devices with the expectation that anything that forces widescreen 480p needs to be adjusted by the GBSC. So, what I'm saying is to do plenty of research and report back with what you learn along the way
I already know I'm going to have some headaches once I start using chained HDMI switches, an EDID emulator for a PS4 Pro, and more obtuse mods.
I also spent way too much time trying to clarify this post and I'm sure I missed a bunch of details. I've been out of the vidya game scene way too long.
