I used Eagle in my first few years of hobby PCB design. It was fine, worked well. I really jumped on KiCad after development started to pick up and Mac support became really reliable. The workflow for managing schematic symbols and component footprints has _massively_ improved. It's definitely more usable. I think shortly after I started using KiCad, Eagle was acquired and that really soured me to it. Autodesk's products are fine, but I don't really care for their business practices. Your noting they were unwilling to honor a license brought prior to purchase is more kindling for that fire.
