I use XSane and TheGimp to scan and edit my paintings, Firefox with privacy extensions to browse, VLC to play videos, Gnome Mahjongg to waste time playing. I used to use Resolve to edit videos, I'll soon start using Kdenlive. As a visual artist I have a thing for film emulation that Kdenlive can't do, but it's something I'll have to leave behind.
On Resolve there various helper for-film-emulation plugins, and also third parties like Dehancer and Cineprint (which are exceptional), that do near-perfect film emulation. These things don't exist on Linux video editors. They barely exist for Premiere/FinalCut. It's a Resolve-first ability.
Film emulation is a whole "sub-genre" of photography and video, where creators are trying to emulate the look and feel of various types of films, like kodachrome, fujifilm, etc. In fact, most movies and music videos have a layer of such emulation during their color grading process. I also treat my videos that way for a more cinematic look.
