I am a very happy user of HyperSwitch: https://bahoom.com/hyperswitch

Allows tabbing through individual windows (one icon per window, not just one per app) and doesn't have the problem of not showing anything after the selection. Downside: it does not include minimized windows.

Although it seems to have been in "beta" since forever, I've never really encountered any problems.

Coming from Linux/Windows, I was always slightly annoyed that you could only command+tab through a single window for each application, but now that I'm used to it and have grown accustomed to command+tilda to switch between windows of the same app I find it nice.
