The price does also play a role. Learning tools and frameworks takes a lot of time, and if it's not a free tool then if you change jobs or even departments you might find yourself unable to get a license. If you want to work on stuff at home, you need to pay. If you want to run a test server you need a license. Some tools are better than others in that regard, but it's basically why I would always choose learning a slightly worse free option than a paid option.
