I feel like everybody got it so serious. I got it as a which one would you choose.
Last time I had to edit something I used olive. Didn't got in my way to get work done. So, I liked it. Olive uses QT instead if GTK. But I use gnome as my DE for some years. I try something else time to time but always get back to gnome.
So between these two, that there are many years I don't try. Just by the picture. I would choose piviti. Qt things use to have way more preferences visibe at once, qt apps looks more advanced tools. Some times this may add noise to get to the few important things/ui elements buttons to get the work done. But my experience with Olive and Mixx that are both QT were really good. Maybe I should try KDE again.
Tell me more about your anger.
