Tried Zen today and it didn't feel right—felt too much like it wanted to be Arc but ended up a bit frankenstein-y in the process.
Open to suggestions that aren't Arc or Brave, if anyone has them!
I'm kinda strictly against Chromium because I first installed Chrome to break up a browser monopoly that threatened the long term future of the web. I uninstalled it once it flipped from "the browser that's making the web better" to "the browser that's making the company Google better at the expense of the web"
It's not really a political stance, but a pragmatic one. I appreciate that makes it hard to find alternatives, but I can't logically justify using Chrome.
I don't use the integrated calendar or mail client, just the browser and you don't notice these features are even there since they don't spam you.
It is chromium based however.
