As an emacs user, I view multi-cursor as suitable for only a subset of macro usage. Macros are inspectable, editable, savable, able to be applied across files, easily used a variable N times.
My typical pattern is something like: define it, try it, adjust it, then apply variable times (including “infinite until error”), maybe save 1% of them. That often takes less time to do than it just took me to describe.
I use macros probably 25x for every one time I reach for multi-cursors, though to be fair, if I came the other way, I’d probably use multi-cursor more often than currently. (I used macros for 30 years before getting multi-cursors, so if both can do the job, I’ll use a macro.)
