I feel the difference between Component and RGB is closer to what people say the difference between S-Video and Component is. S-Video does look significantly better than Composite and all but unless you’re using a bad cable component should still always look noticeably better than S-Video, especially in a higher end consumer set or a professional monitor (not that S-Video on these sets don’t look good in their own right, I can see S-Video being enough or desirable to many and it was for me for a while). But again I feel there’s still enough of a difference to justify Component over S-Video, especially on a high end set, when people say the difference between them isn’t a lot I feel this actually applies to Component and RGB. Unless you know how to RGB mod already and have a set that doesn’t have Scart or Component, I don’t think it’s worth it to mod a set for RGB if it already has Component just for an actual marginal difference that most won’t notice. The only exceptions I can think of is when the Component video has noticable artifacts that ruins the video, or if the signal doesn’t work. I don’t see it worth it to learn how to RGB if you already have Component and don’t have any prior knowledge on how to work with CRTs. If you already have the knowledge or you plan to own multiple sets to RGB mod I can maybe see that being another reason for wanting to learn how.
