Switzerland has some of the world's best universities, sure.
But I don't want to do another degree (the only comparable option would be a 3 year, full time BSc in Computer Science).
Sure, the tuition costs would be lower, but the opportunity costs (plus 3 years of not really working while I study) are easily 10x higher than doing Lambda School.
Plus, a local university won't teach me the skills I need to become a better 'practical' web/mobile developer. It's a lot of (admittedly very interesting) theory, not the kind of vocational training I need.
With Lambda School I could strengthen my weak areas in 3-6months and don't need to travel to do so. A bargain for the price!
