The Bunkspeed forums weren’t too helpful to begin with, so no big loss there.
If you have questions, I think it’s still pretty easy to get ahold of David Randle, who seems to have stayed on board during the transition to Dassault.
I’ve been trying to force myself over to Visualize since it came out, and it is improving. The big deal breaker for me right now is the fact that I can’t send jobs to a remote queue (render farm.) The pluses are pretty big though: Decent auto updating (the scene in Visualize updates when your CAD is updated and saved) and the materials are a little better. There are a couple nice UI changes (illustrated camera views) as well.
One neat trick: You can open Solidworks Visualize files in Bunkspeed by changing the file extension to “.bif”. It even imports materials! That alone is worth the wonky workflow.
