Voyager Series: Which is better, USA or Brazil?

[BarryT]

Hi all,
I'm curious to know people's thoughts, (and facts if any exist?), regarding which design is better made, and\or, more sought after... the USA (####A serial) , or the Brazil (####B serial) versions?

If I understand correctly, the early batches of all Voyagers were made in both the USA and Brazil... am I correct here? Does anyone know of any physical differences, (in build quality), between the two locations?
The later models came out of Malaysia and Singapore, then ultimately, China... and I hear that the quality of the later is so-so at best.

Also, does anyone know if either of the two are more difficult to locate, or more sought after? I.E., if you had two of each Voyager model sitting in front of you, one from USA and the other Brazil, which would you choose, and why?

Thanks.
