I have the same feeling about Germidour... I'd grow it for the beautiful wrappers alone.
My outdoor plants produced larger rounds this year as well, and that's okay because I hope to see a nice sized bulb from them. It was a very hard winter both wet and cold, and they came up early and valiantly. So I'm counting them to be nice and hardy as well.
We used our last bulb of porcelain ( Music or Argentina) a few days ago and they were still good, but I kept Persian Star and Chesnok Red for last, as they are smaller but also they've been my best keepers - some unused ones stayed hard well after the next harvest. Spanish Roja is one of the short keepers, as you said, must be used before the new year or soon after.
