Haven't had a chance to use it much tbh, I mostly work in backend development. I'd deeply prefer it to Electron for my personal ideological reasons (which is that running "native" apps in a browser is stupid), but I hear it's not recommended for web, so you'd still have to develop two or three versions (depending on how feasible it is to keep desktop and mobile on the same codebase - I'm not sure on that). Still, it's more reasonable than doing the desktop versions in Qt in this day and age, because C++ is just a recipe for footgunning yourself. This is of course negated by having significant C++ experience, in which case Qt is the way to go.
