As it stands there are too many open variables in the question to give a definitive answer.

Firstly, any signal that isn't composite is, by definition, component because it is comprised of component parts. This is to say that S-video with it's luma and chroma channels has two component elements, and therefore is a component signal. RGBs (RGB+composite sync) as used in SCART is a component signal.

YPbPr is analogue Component video based on a Luma channel with composite sync (Y) and two colour difference channels (Pb and Pr). It can support a wide range of resolutions. The main ones we're interested in are SD (480i/576i), and the HD resolutions of 720p, 1080i, 1080p.

If limiting our comparison to SD 480i/576i, then RGBs has the advantage. It is three full-bandwidth channels of picture information. Any of the channels will give a full-screen image corresponding to the colour of the video channel.

YPbPr at 480i/576i only has a full resolution image on the Luma channel. The colour difference channels are half resolution each. If you were able to rig up a sync signal and just display one of the colour channels then what you'd see would be colour blobs moving about with very limited detail. In theory then, RGBs is superior.

In practise, it's hard to tell the difference between the two. Other factors play a more significant role in determining the our impression of picture quality.

Where RGBs definitely loses out is in the potential for HD resolutions. This is not because the signal format is limited. It was/is more to do with the limits of data storage on physical media.
