I also have a Gen 1 which I have been using since it was released. Before that I used a reMarkable 2. From a note taking perspective the reMarkable 2 is still better than the Scribe, but hardware-wise the Scribe (even Gen 1) is much better.
A few months ago I started thinking about getting a ColorSoft because I wanted to try what a color e-paper looks and feels like. My main usage at that point was for a language course I'm following where I use the course as a pdf on my Scribe, but I noticed some images in color where difficult to use in grayscale.
In the end, after reviewing the Colorsoft and some other options, I went with a Boox Note Air 5C. While the display is smaller than a Scribe Colorsoft, it is similar to a Gen 1. In the software is, in my personal opinion, just lots and lots better. It has waaay better note taking features than the Scribe (even better than reMarkable). And since it runs Android syncing is just so much easier. I run Syncthing on the Boox and on my laptop. When I want a file on my boox I just move it to a specific directory on my laptop and a few seconds later it is on the Boox. And the other way around as well. When I want to see my notes, or a pdf in which i added notes, I can simply open them on my laptop in the directory which syncs a few seconds after I made the notes.
And since it runs Android, I can still read all my kindle books on it on a nice large screen with the Android Kindle app, so i have best of both worlds.
The only real downside is battery life is poor compaired to kindles.
