I see you've met Bub. LOL

I use jBridge over BitBridge because I like the ability to have the Give all keystrokes to plug in button, stepsequencer button, Read-automation button, write-automation button, and solo button easily accessible on the GUI of my bridged plug ins.
You have to open the plug in GUI while holding down Shift, to have these buttons accessible using BitBridge, and even then it's two windows open, which is not attractive to me.
With jBridge it's one GUI window, which looks nice. :)
Also jBridge retains significant features of my 32bit plug ins. For instance, I still use the DR-008 drum sampler. When I use BitBridge, and save a project with a kit loaded into the DR-008, upon re-opening that project, the kit is not automatically loaded as it is when I'm using the 32bit version of SONAR and the DR-008. And I have to go through the red tape of browsing to load the kit back into the DR-008, everytime!
However, if I use jBridge, the kit I saved is automatically loaded when I re-open a project I saved with a kit loaded. That's a somewhat little thing, but it matters to me. :)
