I would clarify Radisson's positioning. If Radisson is truly "luxury goes exploring", the company ought to develop more interesting itineraries with more multiple overnights in the particularly interesting locations. In addition, I'd look into offering more 10-12 night itineraries. And of course, they need to make up their minds on whether to go truly all-inclusive. Radisson is going to get crushed in the middle. Oceania is solving a number of interesting problems from beneath (not the same level of luxury and service but better itineraries in terms of destinations and length) and Silversea is going to come in from above with a more luxurious product that goes to the same places. Being in the middle is a terrible place to be as the consumer markets become increasingly "hour-glass" in configuration with consumers looking for either the best value OR the best product. I think this is pretty much common knowledge to most people at this point. As others have said, Oceania and Silversea right now look like very good alternatives because Radisson's attempt at a "goldilocks" positioning is not scratching the most urgent itches that a lot of people probably have.
