Rose Clouds of Holocaust is my personal favourite from Death in June as I believe it's the more consistent of the two. However, most people seem to prefer But, What Ends When the Symbols Shatter? which I can understand as it contains a couple of phenomenal songs that may very well be the best in Death in June's catalogue.
You might find it difficult in obtaining these Death in June albums though. Combined, it probably cost me $65 for the two and that is very cheap considering what they usually go for. I find it strange that Infrarot would even have them advertised, unless they've recently been reprinted.
For Sopor Aeternus, I would probably recommend Todeswunsch which contains a more medieval sound with some folk influence or La Chambre d'Echo for a more modern, darkwave but still classical-influenced sound.
