The German table feels better made and is vastly more neutral sounding - great if you listen to a lot of instrumental music (my collection is mostly classical, ECM and prog). Its dynamics are more natural and come from black backgrounds.
The Rega is a wonderfully fast, textured and dynamic table. It has PRaT in a way that the Clearaudio does not. However the sound lacks body and is more holographic than full. I like the Rega for jazz and my classic rock and new wave record. It does classical really well also but the Concept is better for that music.
These are both amazing tables for the money. I have more than one table as sometime I want PraT and sometimes I want neutrality.
