I love QGIS so much. I use it professionally every day. The city I’ve worked for has used it for years.

We are about to bit the bullet on a few ESRI seats mostly for interoperability with some of our consultants and easier use of REST servers and stuff, but we’re getting the absolute cheapest licenses because all the spatial analysis tools thay cost thousands extra per license are free in QGIS, and I can still use it.
