Apple - Best app to switch between all open windows

Hyperswitch is free and works well. It also looks nice:

Here's a list of all the options from this page:
["italicized & quoted notes are sourced from linked url"]

• Mission Control and native keyboard shortcuts: ⌘+tab or ⌘+` (backtick)
• Witch ["v4.3.8 requires macOS 10.10 Yosemite or newer"] [$14]
• Hyperswitch ["Mountain Lion, Mavericks & Yosemite"; works on Sierra & High Sierra] [$0 Free] [window preview]
• Contexts ["v3.7.1 Works on Mojave & Catalina"] [$9 after Free trial]
• Optimal Layout [Snow Leopard or later] [$0 (free) but not currently actively developed]
• Karabiner - ["macOS 11.0 Big Sur, macOS 10.15 Catalina"]
• Senebier ["10.4 or later", last update in 2012]
• AltTab ["macOS 10.12 to 10.15"] [$0 (free), open source]
• Hammerspoon with hs.window.switcher [free and open source]

I'm guessing you're already aware, but for those searching the web there's always Ctrl+F4. No visual feedback, but it does switch between all windows for all apps (that are not hidden) with one command. Of course it's instant and so it doesn't reorder the list like ⌘+Tab does. I also got tired of Witch, but I decided that most of the time ⌘+` is all I need.
