you will find it far better than Netscape Composer - there's no comparison really. FrontPage is very powerful, in fact it's probably the best program currently on the market for designing and developing data-driven pages, and I thoroughly recommend it.
DreamWeaver has become a legend in its own lifetime, and no serious web designer would be without it on the hard drive. There's a pretty steep learning curve associated with the program, but if you have the inclination and the time you won't regret it.
NetObjects Fusion is probably the ideal program for those who are designing their first 'serious' site. That isn't to say that the software lacks refinement or power - it has both in full measure, and is capable of holding its own with anything on the market - but it comes with a comprehensive set of templates, and has a very friendly 'feel' to it.
If you plan to do a lot of design/development work you'll ideally have all three, but if I had to recommend one program for all-round versatility and power it would undoubtedly be FrontPage 2003.
