I made the switch from Sibelius to Dorico when Dorico came out. Have been using Sibelius since version 5, created lots of video tutorials and written tutorials for it over the years, so I was deeply connected to the program. However, now I know Dorico well, I would never go back to Sibelius and when I need to do some work in it, I feel very frustrated about especially creating good looking layouts, something that Dorico does from the start automatically.
