I'm not clear whether your object is to publish the book, but if that is the case, be aware that the vast majority of sales are on Amazon, and that Amazon "requires" both an html (the actual) TOC page and the NCX (virtual) TOC. I say "requires" because books are routinely sold that lack one or the other, but that's the stated policy.
And, for Amazon, I rely entirely on Sigil. The gen on the KDP forums is that Calibre-generated books are sometimes rejected. This complaint is less common now than formerly, but it still crops up from time to time.
I love Calibre for one personal project: my university library stocks increasing numbers of titles in digital format that can be downloaded either as PDF files or as epubs for reading on ADE. I take the epub and convert it to mobi for reading on my Fire tablet. But I don't like the styles that it creates; Sigil does a much finer job of employing my own style sheet.
But I am really a doofus at all this, so FWIW.
