Zen browser is my daily browser since many months now. Most of your fair criticisms I have solved with Zen Mods and playing around in the settings.
The Widewine limitation is really why I will always keep another browser to fall back to: I recently discovered that all of Udemy is non-playable in Zen.
I’ve started using more Zen Mods recently too, the most important one I would say is Zen Context Menu - which lets you de-clutter the options when you right click anything. There are way too many options being shown when you right clicked the sidebar, but it’s a lot nicer to use now.
Looks just like Arc

It’s a straight up copy. Somewhat similar… JFC
But open source and built from Firefox
One way to solve the “content appearing offset to right” problem is to move your tabs to the right side. Works pretty well for me…
