Smashwords uses an automated formatting program for their ebooks, so if the author publishes through Smashwords then they should be basically the same. I believe authors can, if they choose, upload their own files to Amazon, which should in general be better formatted than Smashwords automated output. I don't know of any way to tell except to compare samples to see how they look.
I only buy or download mobi files. They don't require conversion, and since Smashwords formatting is automated, the files should all be basically the same.
I'm not that familiar with Smashwords, so I'm sure someone can correct me if I'm wrong.
