Qt4 is/was much better than Qt3; and Nokia made it available to everyone under LGPL which was sensational; Qt5 mostly improved modularity and platform abstraction; after the Nokia aera, Qt has given itself a bit of an orientation log, adding features in all sorts of directions that didn't necessarily add to the core proposition, but increased complexity and development effort, without adequate value in my view.
