People will say that GIMP cannot compete with Photoshop in some use cases, I'm just happy that I don't have to worry about those and it's completely sufficient for what I want to do, same with LibreOffice vs MS Office and other imperfect FOSS projects. They might not always be the best choice out there, but they’re almost always decent.
I run Linux, and dearly miss being able to use Fireworks. My attempts to get it running on Wine in the past (probably a year or so ago, if not more) were not successful, and I haven't been able to find anything that feels like a suitable replacement for working with vector graphics. It is a genuine (perhaps irrational) point of sadness.
I'm still bitter that they killed it off.

Also their is protondb which tracks game compatibility:
FYI, I have Macromedia Fireworks MX running perfectly under WINE on Fedora (I think the only tweak I did was to increase the font size to cope with modern HIDPI displays). Highly recommend it as a web-friendly image editor (it was what I used before Adobe killed off Macromedia).
