I'm on pop os with gnome but using dash-to-panel to get a more classic Taskbar look. I love that extension and seems extremely well supported even across upgrades, it's so good I donated. Maybe I'll add a screenie later.
As for op's pic, I understand liking a particular setup, but to use their proprietary icons too seems strange to me. To each their own, I guess. I thought it was literally a mac on a Linux /c.
