They look a bit funny and take a bit longer to start up. If you are on a Gnome desktop then the GTK libs will be already loaded when you try to open Gedit but its gonna need to load all the Qt libs into memory if you want to open KolourPaint. IMO, its more of an inconvenience than a big deal breaker.
