In many ways it feels like the number one change Adobe did to Fireworks is to make it slower, for no discernible reason.
And Fireworks is quite buggy in some details, and it being a completely different codebase didn't help. I agree that AI and PS are much better in terms of stability and codebase and support, but they still feel like you're using an electric toothbrush to paint a wall.
For print graphics, it's LaTeX for me. It's not an entirely sane choice. Either that or very high resolution Fireworks, trying to deal with HTML5 (and bending that into a PDF with horrific results) or just giving up and using Word. Or Illustrator, for that matter, which is the sane choice. But Illustrator sits in an awkward gap and InDesign isn't much better either in that regard.
There's a market out there for a non-WYSIWYG application for print design.
