The Scandinavian seems to be getting the vote from all here, and I would echo that. What I would say about the Plaza is that the views are stunning from the business floor rooms, or for that matter from 34 Sky Bar out to Holmenkollrenn. You can even see the ski jump floodlit if you know what you're looking for. They also have a sauna up here with views through plate glass windows looking east.

If I didn't have an apartment now I would stay at the Grims Grenka followed by the Scandinavian.
