need some help with using my ps2 on my hdtv?

I currently use component with my ps2 on my hdtv but I've seen 3 converters that I been wondering about. one is a ps2 to hdmi the second is an A/V to hdmi it's usually a small white box the third is a component to hdmi. I've only seen comparison videos of the (ps2 to hdmi) and the (a/v to hdmi) and the ps2 to hdmi seems simaler to component quality and the a/v to hdmi seems to have good results but that's comparing it to composite since that's what plugs into it. So basically I want to know how do these compare to the quality of component and would these fill out the screen of the tv better. Because the ps2 has a small border around the whole screen when in 16:9 and on the top and bottom when in 4:3.
