This is so often repeated, but I genuinely don't understand why. Could you try selling me on it? I ended up going the sysadmin/devops route instead after college, but the more I learn about Linux, the less I understand why anyone would choose it for personal, active manual use.
I can understand server deployments, it works well enough. It's available at no cost, Windows Server is way out in the far other end in terms of current desired behavior, and whatever pains it has you get paid to make up for. None of which applies on a personal device level.
The most common selling points I see are more performance and less "spying". I find neither of these very persuasive, and I'm not interested in ideological rationales either (supporting free software). If you have anything else, I'm all ears.
