For Windows I fiind ClickMonitorDDC[1] is a great app as it has more configuration options, and also lets you control other parameters such as volume, contrast, RGB, color profiles, etc., and also lets you control these individually via the mouse wheels scrolling over the tray icons, which for me is a must have UX wise.
Yes, that one is really good as well and I recommend it for more advanced use cases like setting manufacturer specific VCPs (e.g. E9 to 36 for PBP on Dells etc.)
But most people ask me for a Lunar alternative which by that they mean a pretty UI with some adaptive or automated brightness. That's why I usually recommend TwinkleTray.
