It has definitely matured, but the workflow is pretty different from something like Ableton or Bitwig. I use it because it's what I learned to produce with. The Edison plugin that's bundled is worth the cost of licensing alone.
All in all, once you get to a certain level of knowledge around mixing and mastering, the debate over which DAW to use is much like the vim vs emacs debate. As long as you're proficient in the software, the end result will come out looking more or less the same.
I will say Ableton and Bitwig come with a nicer set of default plugins and samples.
By far the most difficulty I have in making electronic sound stuff anymore is finding a UX I can work with, much less compose quickly. Like in this context, SoundForge was absolutely ruined by Sony, which probably pushed me to CoolEdit Pro, and now Audacity, none of which are as good as SF5(?) was.
It feels similar to how GIMP and Audacity are being ruined with developer-imposed format friction right now.
