Count me as someone who uses Scrivener every day, too… AND I use Obsidian and Ulysses as well. They all have their uses because I spend a lot of time writing, reading etc.
Scrivener: long-form writing.
Obsidian: “thinking”/ exploratory writing. Research notes.
Ulysses: client gigs/ blog posts/ anything short. (I love that I can save a client project directly to DOCX, then send it to the client. Also that I can post directly to my blogs from Ulysses.
I’ve tried using Ulysses for long-form writing, but I’m too set in my ways with Scrivener. I use Ulysses for blog posts and short material, but I can’t see myself writing a book in it. 
As for Scrivener updates; the app does pretty much everything I could imagine and more. So I’m OK without the developers adding constant frivolities. Few people use Scrivener to its full potential as it is.
In short, I love Scrivener as much as I do Obsidian and Ulysses. We’re all different; we use what works for us. 
Happy writing to all, no matter which apps you use.
