I believe both are fungicides.
Are there advantages of one over another?

@Franp
There are other fungicides to choose from as well. Advantages vary by crop and location.

I have been looking at these publications which are updated yearly:
Geared towards home growers - 2023 Pest Management Guide - Home Grounds and Animals | VCE Publications | Virginia Tech
Geared towards commercial growers but has lots more information - 2023 Spray Bulletin for Commercial Tree Fruit Growers | VCE Publications | Virginia Tech
