All of these text editors are console based applications which make them ideal for editing files on remote machines. Textadept also provides a graphical user interface, but remains fast and minimalist.
Console based applications are also light on system resources (very useful on low spec machines), can be faster and more efficient than their graphical counterparts, they do not stop working when X needs to be restarted, and are great for scripting purposes.
I have selected my favorite open source text editors that are frugal on system resources.
