I think which is "better" depends on what you want to do with it. The A201 is probably better suited for fingerstyle (cedar top and auditorium body = very responsive and balanced sound), the D200 should excel at flatpicking and vocal accompaniement, and will have more headroom for a heavy attack.
I've never had a chance to compare a Czech made with an Irish made Avalon, so I cannot say if there is a difference in quality.
The Ellipse blend is perhaps a more versatile system because it combines the undersaddle transducer with an internal mic, giving a more natural sound. On the other hand, the Prefix has EQ controls...
