So far the experience is very nice. Many things work remarkably well and are relatively easy to implement when compared to traditional UI work on Android or Swing. Of course there are also a few problems that will hopefully iron out when Compose for desktop matures. Some unsolved problems we've run into have to do with layouting in material dialogs, accessibility not working on Linux and emoji support. There's also some issues that probably are less likely to run into on Android that have to do with keyboard navigation where it's possible to navigate to UI elements that are behind a modal dialog and interact with them.
