<br>In terms of quality component and VGA are basically identical. VGA is RGB color channels plus horizontal and vertical sync channels. Component video provides the same RGB information just it uses different channel definitions. Component channels are luminance ( Y = R+G+B ) and part-Red, part-Blue channels ( Pr = R - Y, Pb = B - Y ). Six of one half a dozen of another.
<br><br>The real factor that might make a difference is how your TV/monitor handles VGA or component video. Like my TV has a whole bunch of extra display settings for VGA input that the component inputs don't have (not that I have ever used those settings).
