The reason Vim has outlasted every other editor in my workflow is that the editing model is a language, not a set of buttons. Commands compose: an operator plus a motion, so ciw changes a word, dt) deletes up to the next paren, yi" yanks whatever sits inside the quotes. Once that grammar is in your hands you stop thinking about keystrokes and start thinking about edits, and the speed that comes from that is hard to give back once you have it. The fact that some flavor of vi sits on essentially every Unix and Linux box is the other half of why it stuck. I SSH into a server I have never seen before and Vim is already there, behaving the way it does on my own laptop, which means the muscle memory I built once keeps paying off on machines I do not control and cannot install anything on. It starts instantly and it stays out of the way. I type vim and a file name and I am editing before a heavier tool would have finished drawing its window. It barely touches memory, which matters on the tired jump boxes and cramped containers that always end up being the thing you have to work from, and it opens files that make graphical editors stall. Tailing a multi gigabyte log to find what just blew up is a normal Tuesday, and Vim loads enough of it to be useful without falling over. It is not a flashy tool. Dependable is the word I want for it, and it has earned that over years of not letting me down at the wrong moment. The search and replace engine is the feature I would miss most in day to day work. The full regex syntax behind :%s means a rename or a reformat across a file is one line, and ranges let me scope it to exactly the block I care about instead of the whole buffer. The global command, :g/pattern/ followed by another command, is the part people underrate. I use it to run an edit on every line that matches a pattern and leave the rest untouched, which turns a tedious manual pass into a single instruction. Macros cover the cases too irregular for a substitution: record once with q, replay with @, and a fiddly repeated change across two hundred lines is finished in a handful of keystrokes. This is the point where the editor stops being a text box and becomes a small automation tool I keep in my hands. Diff mode is the piece that quietly justifies keeping Vim set as my git mergetool. It lines up two, three, or four versions of a file with the differences highlighted, and :diffget and :diffput move changes between them without me hand copying anything across. Resolving a merge conflict during an SSH session, on a box where no graphical merge tool exists, used to be the kind of thing that made me want to get back to my own machine first. Now it happens in place, in the same window I was already working in, with the same keys I use for everything else. Because it needs nothing more than a text connection, Vim fits the way I actually work rather than fighting it. It runs inside tmux, survives a dropped link when the session is held open on the far end, and behaves identically whether I am at my desk or three hops deep behind a bastion on a high latency link. Remote desktop and GUI editors are miserable on a bad connection. A terminal and a keyboard are all this asks for, and on the days things are going wrong that is usually all I have to work with. Customization is real, with the honest caveat that you are the one doing the building. My .vimrc is a single file in a git repo, so a new machine goes from a stock install to my full setup in about a minute: clone, symlink, done. The split windows (:sp and :vsp), the buffer list, the named registers, and the quickfix list for driving edits off a grep are the parts of that setup I lean on hardest, and once they are wired the way I think, the daily experience is fast and quiet. Plugins extend it further through native package loading or a manager like vim-plug, though that is a project you maintain over time rather than a store you shop in once. The newer Vim9 scripting dialect is a genuine step up, and I say that as someone who wrote plenty of the old vimscript and never enjoyed a minute of it. Config and plugins written in it load noticeably faster and read more like a conventional language, with proper scoping and closures instead of the quirks that made the legacy version a chore to debug. And the whole thing is free and open source, with no account to create, no telemetry phoning home, and nothing nudging me toward a pro tier. The licensing even routes donations toward children's charity work, which is a pleasant thing to know about a tool I run all day. The community maintaining it now is clearly committed to keeping it alive, and that counts for something when you are building a long term habit around a piece of software.

The integration features and overall ease of use make this product very user-friendly.

It is easy to use and has a good feature, just like copy and paste.
