IMHO the major difference is that Adobe Reader is a 3D viewer with quite a 
userbase and lots of support resources behind. While the failure of 3D 
community to accept U3D as 3D JPEG is deplorable, PRC prospects in Adobe 
seem bright - they have bought the format together with the authors, make 
noises about submitting it to ISO, released documentation...

format, but figuring out what are the limitations of Adobe viewer takes a 
lot of time.

I do not remember if that applies to Blender, but googling showed me that
in 2006-2007 people asked questions in lists/forums of 3D software 
pieces about 3D PDF output, but neither users were interested, nor 
developers excited.

        Sincrely, Michail
