What you would be giving up
Sigil is most often brought in for fixing an epub that a retailer validator has rejected, without re-exporting from the tool that generated it, correcting the table of contents, reading order or metadata in a file supplied by a conversion service, preparing a back-catalogue title where the only surviving source is the epub itself, applying a consistent stylesheet or a bulk text correction across every chapter of a book at once. Anything replacing it has to cover the ones you actually depend on, and a cheaper tool that misses one of them is not cheaper.
Two things this page cannot settle. It compares on price, model, tier count and rating, because those are the fields the category listing carries, feature-level differences need both full records, which is what the head-to-head pages load. And the ratings are third-party aggregates imported with each entry rather than reviews written here, so a 0.2 difference between two tools is noise rather than a finding.
If Sigil is broadly right and the question is cost, the Sigil pricing breakdown covers every tier and what each one adds. If you want the whole field rather than a shortlist, the Publishing category lists everything the directory holds, and best publishing tools ranks them.
Sigil runs on windows, macos, linux. Platform coverage is not carried on the category listing for the alternatives, so it is one more thing to check on each head-to-head page rather than here.
