I will say 2 lanes roundabouts as a cyclist are a little intimidating when you need to take the inside lane. Drivers are not looking for cyclists the way they look for cars or will rush to get ahead of you or just try to bully you out of the way by entering the roundabout across you illegally and daring you to take the right of way. At particularly busy examples I will dismount and take the pedestrian crossing.
Junctions have their own problems though: Usually drivers will not permit a cyclist to merge in front of them while traffic is not stopped, which means if the stream of traffic is continuous you need to plan your lane change when traffic is stopped by lights.
As a pedestrian, roundabouts with islands (aka all roundabouts here) are vastly superior.
