To me I need to see the open programs and the amount of windows of those. Also maybe because of familiarity never got used to title bar of app and status bar both being on top of the screen to me this layout is more sense. Anyways also tried KDE which would require less extensions but the issue was weather, clock style and other minor things I could not tweak/fine tune to look right for me.
The first only rounds screen corners, adjusted so that the border radius is similar to my laptops bezels. The second one rounds(and adds outlines) to all application windows.
