Certainly was in its infancy, Mesh. People bought it for that very reason of a few problem plug-ins. Plus you could get him to work on individual problem plug-ins, which was handy. I only used it overcome memory limitations so I can't answer your specific question.
+1 - It seems to depend on the plugin and the version of SONAR, as well. Sometimes Bitbridge seems to do a better job, sometimes, JBridge does. But it is nice to have options. JBridge also fixes some of the pains about working with Bitbridge (not staying on top for one) and has a bunch of gui tweaks that facilitate the process of using 32 bit plugs. Sampletank is one I have had better success using with jB over the years than BB.
As more plugs go 64 bit (Just downloaded VB3 64 bit, which was one of the plugs I needed jBridge for - seems to work great) it won't be an issue.
