I disgree, as I personally dislike the incorrect formatting that the Kindle software imposes upon the text.
I HATE AZW3 and will not use it or recommend its use to other Kindle users!

The thumbnail used for books that came from Amazon and still have a valid Amazon ASIN will be uploaded by calibre, but a converted and sideloaded book will have the cover extracted from the .mobi; if that thumbnail is uploaded by calibre, it doesn't matter what the actual ebook-file's cover is, your Kindle will use the thumbnail on the home screen anyway. However, I can assure you that either way the .mobi itself will retain the same cover until you perform a mobi-to-mobi conversion. (IIRC it will add a new cover at the beginning and you will have two covers, one after the other.)
This is a well-known and documented fact about the .mobi format!
As a result, the following problem appears -- an amazon book will get a new thumbnail, so you think the cover has been replaced, however, a book converted to mobi and "updated" with a new cover will staunchly refuse to be updated. This becomes clearer when you look at the actual "first page" of the .mobi ebook, which will be the cover image. It hasn't changed either time.
I don't know what problems you have with the azw3 format, but clearly those are a matter of preference -- the only difference I've noticed between the two while reading is .mobi doesn't split hyphens across lines.
