Proprietary DAWs? By that I have to imagine you mean FL Studio, I don't think anything really holds a candle to that, especially because I'd also have to include the myriad of propetary plugins too (even if you can technically use them with free software). I've used it to make a few simple jingles and whatnot for myself, and also to just jam on my MIDI keyboard, which is really all I need anyway. Zrythm is a bit more robust with plugin support, but the 1.0 release is certainly rough around the edges at the moment.
I do largely just install things, but I like to go to source pages, about pages, try and get a feel for the vibes, and ensure it is actually free software before I use it. It just set off a red flag and I wrote it off; maybe the software is great and there's nothing to worry about, I dunno.
