The ones marked for strength (plastic box) also run quite soft. A 3 feels like a 2. So in that regard at least, they are way different from Vandoren traditionals.
The file cut is more precise on the plastic box ones than on the ones in your photo, but still not as precisely machined as a current-production Blue Box Vandoren.
I can say that (compared to current-production Blue Box Vandoren) the blanks tend to be thicker than Vandoren, the spine and shoulders are definitely cut thinner, and the tips are thicker. But they don't appear to be as precisely machine-cut and consistent as a modern Vandoren.
