"I find traffic signals much nicer as a pedestrian"
You may find them nicer, but they are not safer. The data already shows roundabouts are safer. As the article reports: "researchers have found that roundabouts reduce [...] pedestrian/cyclist incidents by 40%"

That study was specifically in the USA, whose signalized intersections are not really pedestrian-friendly to begin with. For example right-on-red is permitted almost everywhere (except NYC). In that context, I could believe that roundabouts are less bad. I would be interested to see how the comparison generalizes, for example a study of roundabout vs. signalized intersections in Denmark or Germany. It's still of course possible my feeling of more safety at signalized intersections in Denmark is wrong.
Sweden takes an interesting approach in combining both. There are a lot of roundabouts, but most of them also have a signal at the entrance. This makes it easy to cross as a pedestrian, because your crosswalk at the roundabout entrance is protected with an exclusive signal cycle. That forces a gap in traffic instead of you having to force the gap by trying to step out. Possibly even safer than either option alone?
At lower-traffic intersections the difference is less pronounced, partly because it's easier to force your way across even without a signal, and partly because the signals at less busy intersections may not give pedestrians an exclusive period in the cycle anyway (e.g. by allowing left turns on a regular green).
This might be Copenhagen-specific, but in Copenhagen I also find roundabouts make the pedestrian/bicyclist interaction less clear. At regular intersections, bicyclists can't cross your path when you have a walk signal, but at roundabouts they seem to just go through and are less likely than cars to stop preemptively when they see a pedestrian wanting to cross. Roundabouts aren't very common though, so maybe this would be worked out if there were more of them.
