I did a short evaluation a while back (while support for desktop/web was still in beta so much has probably changed), ended up going the PWA route. Developer experience was fantastic, code completion/debugging/documentation/compiling were all great and smooth experiences, Dart was easy to pick up quickly although some of the code generation stuff such as serialisation/deserialisation was a bit clunky. However the deciding factor at the time was that the end result felt very much like a mobile app forced into a desktop environment, things that users expected to have like copy+paste weren't there, keyboard shortcuts that users took for granted were a hassle to reimplement, the scrolling felt 'off' in a desktop environment and performance wise it could feel stuttery quite often. I quite like the fundamental ideas behind Flutter (a lightweight GUI runtime that can produce consistent results across many platforms) so hoping these are already or on their way to being ironed out
