I personally think that with the dry-plates at times, especially depending on the make up of the collodion and the way they are developed, they handle detail better and have more evenness of development across the plate than wet plates. You also have the benefit that in landscapes for instance you can eaisly take advantage of the f/stops and not have to worry about getting a quick exposure because of the time factor and fear of the wet-plate collodion drying out too fast. The defects cause by too hot or too clod weather are also not an issue.
