I think the differences would be the following ones: - You wouldn't have to bother with JS files, they are removed from saved pages by default. - You couldn't (easily) de-duplicate resources because they are embedded in base64 into the page. However, SingleFile can detect all the hidden elements and unused CSS rules/declarations (by computing the cascade). So the HTML and CSS are optimized. It is also able to group duplicate images (by using CSS custom properties). There are other options to make the document size as small as possible. Most of the time, pages saved with SingleFile are smaller than Chrome MHTML files. - The saving process would be much more simple, reliable and could be automatic. - Videos wouldn't be saved (by default), a snapshot of the video would replace each video. - Maybe the "filename template" in SingleFile would help you to organize things.
