In? Out?
Turn about?
I think that with the improvements in the Built-In Sun speed and with 8 core machines, LW is still "in" for progress imagery, but improvements in Artlantis really indicate that it is now productive enough to justify its expense and the inconvenience of file transfer for final work.
In theory, LW is potentially tops, however, it is clearly not a GS priority to provide Archicad with all of the features they have licensed. LW has the potential to outstrip Artlantis in every way, but that is not they way it goes these days.
