I don't think you can meaningfully compare open workspaces to cubicles without talking about how densely people are packed. I really like the open plan office at my last job, but that was because people were spread far enough apart. And we had side rooms for taking phone calls, having discussions, etc.
I've been in an open workspace that had three or four people to a desk and it was a nightmare. Now I work at an open workspace where everyone is spread out and it is much better. The closest person to me is ~2 meters away.
