Multiple cursors aren't really any different from regex for editing, but are much easier for the layman to pick up and often much quicker for edits where the regex would be complicated and verbose. If my edit-scope is within a single screen or so, I will almost never use regex before multiple cursors. They are incredibly useful for writing new content though (just think about all the times text or code is structurally repetitive with lots of identical boilerplate).
