If you can find a way to convert the LGEO-enabled POV models into a format you can get in Vue, that would likely produce that best quality, since the LGEO models of the bricks have higher detail. However, I'm not sure you're going to be able to find a way to do that, as the POV format is extraordinarily complicated, and normally things are modeled in another format and then converted to POV format.
LDView supports export to 3DS format, but there are a few problems. First of all, its computed smooth normals don't make it into the export, so you end up with a faceted model. Secondly, the released (even Beta) LDView has serious bugs in the 3DS export functionality. However, if you want to give it a try despite the faceting (which you may have some other way to deal with), contact the LDView email address, and I'll send you a developer build, which has many bug fixes in the 3DS output.
