Smashwords for larger distribution?

I’m seriously reconsidering Smashwords. In order to publish to the number of platforms they do they require most of the formatting to be entirely stripped out of the manuscript and for it to be uploaded as a word document. When I tried to convert from a word document into the Kindle or even Nook platform it did really weird things to the formatting. I don’t want to spend days fighting with formatting to end up with a very cookie cutter style just because it’s the only thing they can get to go through their own “meatgrinder” software. I think I’ll just look into uploading to the various platforms myself. most of them take an epub format which is what the Nook takes.
