While learning vim/emacs and CLTs may not make you a better programmer, but they can absolutely make you better at understanding and using your tools effectively.
One simple thing I like to do at every job is setup an ansible playbook for the team I'm working on. What ansible allows is me to setup a tool to download all the relevant languages, binaries, create company specific repos for directories, establish a foundation of common CLTs, automatically install software, and fully setup all the paths. Now any person, old or future hires, can literally set up their machine in less than 10 minutes; an activity I see people usually give a full "week" to do.
This is just one example of being more productive with these tools. What's nice about vim are vim motions, they become extremely intuitive and all the supporting libraries, plugins, and other CLTs utilize these vim motions which makes productivity extremely nice.
