If the app lives in full isolation and your focus is data ownership desktop is probably better, but I struggle to understand how it can be better tech for any other use case. I work in a big company so maybe I am biased but 1) every app eventually has to integrate with some other app; 2) every app eventually is used by more than 1 person; in both 1 and 2 desktop pretty much breaks (unless you use version control for 2). In fact we are still dealing with desktop issues as we port this amazing 80's-90's MS era workflow into the cloud and still train users to "save" files.
