Sure GTK+ developers would contest anyone saying Qt is lightyears ahead but I think there are few people who can honestly argue it is not the case - of course, GTK+ has a much smaller scope than Qt but even then, it isn't very realistic to expect the handful of folks working on GTK to have kept up with the hundreds of engineers who were hacking on Qt for the last 10 years...
Maybe the splitting up of Qt in various libraries will help in the regard of the "do it our way" but it'll always be like that to some extend I suppose.
