I know not everyone likes using vim but I thought those who do could share a good reason to get into it. For me its the repetition of the last change with the push of the dot key. Replace the current word with another and move the cursor to the next word you wish to replace. It makes the editor so versatile and feels very satisfying.
I use vim macros all the time. For example, you have a bunch of lines that need the same 3 operations done:
"at the beginning of the line",at the end on the linePress
qa, do what you need to do on one line and go one line below, pressqagain to stop recording the macro, then you can do it 50 times with50@a.
