Leaning towards DriveWorks, but TactonWorks looks interesting

I have pushed Design tables as far as I can, DriveworksXpress has given me a good start and a demo set for the decision makers.

I have a quote for DirveWorks, I also have a history with the people there, good folks who are competant and quick with a smile.

Is there any advantages with TactonWorks?  Both software packages demo well,but I only know companies with DriveWorks.
