QGIS is great. It's a slightly janky version of ArcMap, but ArcMap has always been janky anyway, so it doesn't matter for most things. And QGIS is super extensible.
There have been so many random times that QGIS has helped me out over the years. Thanks to everyone who has contributed to it!
QGIS is janky? It's quite possibly the smoothest and best running GIS software available today. Most built-in tools run way faster than AG Pro, and once the move to QT6 with 4.0 is complete this october, we'll finally get native builds on M-series Mac as well.
I couldn't even know where to start listing the upsides compared to ESRI offering, fron PostGIS integration all the way to the simplicity of plugins.
