Quake 1-3. Q3 was my favorite. Docker. After using it with almost every web I've developed since 2015 I think they delivered on what it promised to do. It's not a 100% quality of life improvement since certain things take a bit longer to do vs not using Docker (starting containers have a penalty, installing a new package dependency takes a long time to build since layers aren't diffed for changes, etc.). But overall I've found it very much worth using.
