Vim is fast, in performance and in productivity. Every key has a purpose, which you can define it to whatever you want, and create your own macros. Everything is a shortcut, which makes it very easy to navigate, replace and much more. For example, replacing is very easy in vim: you can use substitution, r key, while in other IDEs you need to go to a menu or press on some button or other but not as easy in vim. For me navigation in vim changes my productivity, in terms of getting to EOF, end of line or other. This is my personal opinion, but you might feel more comfortable with a normal IDE. Also note that learning vim can take some time and patience is a must.
