I didn't discover it this uear, but I started using QGIS professionally when the small city that hired me to, among a lot of other duties, be the new GIS department.
Turns out they thought ArcGIS cost the same as like Office or Acrobat, and they didn't budget for it for the fiscal year that started 2 weeks before I started working.
Anyway, I've gotten pretty good with QGIS, and we're sticking with it. It does everything I need it to do, and I can still pull stuff from most REST servers.
As a GIS person all I can is ...fuck yeah. I'm for better or worse deeply embedded in the ESRI world but I've started dabbling in FOSS GIS software and honestly it's all damn good. I don't understand how ESRI charges what they do. Also, FME is amazing if you haven't tried it yet (not free or open source) but awesome for quick visual development and data ETL.
I will give ESRI credit for their online stuff. It's expensive, but it's also pretty great. We're actually thinking about getting an online subscription but no software licenses.

ESRI is in the position that Microsoft and Adobe want to be in, a de-facto monopoly.
We've been using QGIS at my company for almost 8 years at this point and I really love it. The python integration and deep plugin repository render it head and shoulders above ESRI. Although I admit for enterprise solutions many will still require the turn-key solutions esri offer.
