Emacs (shortened name from "Editor Macros") has the fastest Regular
Expression engine in the world--when you compare the engines that are
programmed to find and display character strings AS YOU TYPE THEM.

So, just hoping you keep that in mind: As far as editing documents and
searching documents and in some cases replacing strings, there is nothing
faster than Emacs and its native regular expression engine, which is built
for editing tasks--editing tasks that are especially related to and
programmed for searching strings and/or regular expressions as you type
them in

In many other ways, of course other engines are faster; but, not for
editing and searching and replacing tasks

And even when you talk about editing multi-gigabyte and even multi-terabyte
files--suggest you look into and try out vlf-mode (i.e. "Very Large File
Mode") for that, just for the fun and excitement of it, if for nothing else.

So, again, GNU Emacs is by far the world's most powerful editor, and it has
been for many, many years--there is no need for 3rd party tools, maybe
there's a need to investigate the "engines under the hood" and why they
work the way they do.
