I try to when I have a choice. I’ll normally pick gtk apps over qt counterparts if they’re roughly equivalent feature-wise because my DE of choice uses gtk. That being said in some instances there just isn’t a gtk application that has the features I need. A good example is Kdenlive. There just isn’t anything gtk-based that comes close.
I just avoid qt altogether.
