No, none of it is better than Word, and whatever software you use, you’ll probably have to run your writing through Word to make sure it stays compatible with editors and agents, anyway.
In all honest, some of the writing software out there is so bad it almost guarantees failure, and the rest of it doesn’t do anyting you can’t do in word. It’s not the software that matters, it’s the wetware.
In all honesty, I don’t know a single pro writer who uses writing software, with the exception of a couple who have a stake in it.
Save your money.
