calibre's conversion has some issues with the ePub standards since ePub implements a subset of the CSS2/3 and enforces some html/xhtml bits that have been deprecated for many browsers. For instance, most browsers do not require the <!DOCTYPE> anymore while the ePub specifications still mandate this.
My process when I must convert HTML to ePub is to do the conversion in calibre since it gets rid of much of the header cruft that is not used/needed for an ePub. After this I open the ePub in Sigil and do the cleanup and any editing in there. Sigil as an ePub editor is a lot more concerned with being ePub specification compliant than calibre and that makes my life a bit easier.
The other posters here who suggest using either Microsoft Word or LO Writer saving as docx and then converting that with calibre or importing to Sigil as being the easier path are correct as long as the author is careful to use styles to format the document (header, paragraph, etc.).
I've received some .docx files where the author treated the screen as a glass typewriter and they are a pain to deal with. With those, the easiest route I've found is to save the file as a text file and then add the styling in Sigil.
