Id rate ClubWorld fairly low in the rankings... aside from the partition/eye contact thing the seats are also really narrow, and its a pain in the arse getting out if you're in the window seats (and the aisle seats are very exposed).
Agree Clubworld is probably the most average of Business class experiences. I actually don't mind the (window) seat, it is fairly private and I like that. The service and food is extremely average though. It is definitely not an aspirational business class. That said it is better than a lot of the 3 star airlines who still have old style business class seats which is why I would rate it as average, rather than poor.
Or to be put it another way, I find BA Club World to be acceptable and comfortable but is in no way an "experience" to get excited by unless you have never flown business.
