Frontpage was notoriously horrible. It'd make pages that usually looked the way people wanted them to, but the source was a total mess. It was full of redundant and unnecessary tags. You could spend ages cleaning up HTML written in frontpage but if you put in the work you could decrease pageload times and file sizes significantly. Personally, I avoided it at all costs and stuck to text editors. Frontpage was so terrible that it made me resist using Dreamweaver at first out of fear that it'd be just as bad.
