Answering your question: VLC for multimedia, qBittorrent for torrenting, Krita is better than Photoshop for painting, but it isn’t the best image editor (although is really good). Blender is “jack of all trades, master of none” case, where it’s not the best at anything, but is very good at everything.

Edit: I forgot to mention Handbrake, which is basically a frontend for ffmpeg, but is really good.
