Depends how much time you spend in a text editor. If it is just for a few config edits and stuff, honestly there is little reason to learn. The real benefit is if you spend a lot of time editing text due to the time saved using more powerful commands. There is the additional benefit that vi/vim is installed on practically any Linux box, so you will almost always have a familiar editor to hand in an unfamiliar environment.
