Windows runners consume 2x minutes, Mac runners consume 10x minutes [0]. Free projects only get 2,000 minutes per month so running on all three platforms means you only get 1/13th of the minutes of only using Linux. I rarely use anything but Linux runners even on my paid projects. I like saving money, so unless I really need integration testing on Windows or Mac, I don’t do it.
