What basis do you have for saying it's "better" than the other approved HAE drugs?
The half life of Rhucin, 3 hours, is unsuitable for prevention so that nixes the better than Cinryze.
For acute, I don't know how you can compare since they haven't been tested head to head. Rhucin is effective for treating attacks but a quick look at the data showed a median time to sympton relief of about 30 minutes for Cinryze (and I assume similar for CSL) versus 1-2 hours for Rhucin.
