evil-mode lets you do things like "insert this text into the same position in a block of consecutive lines" using rectangular selections. I find it occasionally very helpful. It's a little clunky though: you make the selection, press I, edit the first line, press esc, and then the other lines get edited the same way. (I'm not sure what "the same way" means if you delete a bunch of text or move the cursor around while editing.)
I haven't used multiple cursors, but I imagine they'd let you do that, but with the other lines getting updated in real time, and without requiring the insert points to be neatly aligned.
