The short answer is no.
Slightly longer: depends - different editors have different emphasis so your papers may be easier to write in them. However afaik, they all follow much the same paradigm.
You'll have noticed how useful PFLaTeX is in these forums?
You can also get a plugin that lets you use it in Word ... never used it myself though.
What everyone at the high-end does, they use LaTeX to write the whole paper.
You can get powerful free programs that will let you write LaTeX documents for any platform and the discipline is well worth learning.
(These programs can output to almost any format and there are converters to any other format. So if a teacher is boorish enough to absolutely insist on Word files, you can still do that.)
