I don't think there is anything that is that unique.
However, depending on how you use it, you might need a bunch of other 
tools to accomplish the same.

It obviously is an editor. But it's also a programming language that can 
be twisted into doing a lot of stuff. If you are familiar with sed (a 
Unix tool), it is somewhat similar. But I'd say TECO can do more. 
Obviously the original Emacs was written in TECO. There are other 
editors written in TECO as well. I sometimes use it when I want to do 
somewhat more complex operations over larger text files where the 
changes are a bit more complex than just search and replace.

But writing code in TECO is arcane. It has been described (and not 
without merit) as a write-only language. Reading it, it looks mostly 
like line noise. So it's unlikely that most people know it, or want to 
learn it. So these days, it's mostly old and weird people who might ever 
use TECO. There might, of course, be various tools and programs existing 
that are written in TECO, that people use, without knowing how to write 
TECO themselves...
