I think both are good if you are good at it so pick based on what you can exceed at. And don't put your mindset on getting hired only focus on something you can create. With computer science there are lots of freelance opportunities. And you can create a digital solution you can sell. With architecture you can get your first 2 clients with low price but you can do a great job to build your reputation. Which can grow to your own firm taking on realestate designs and creating unique packages you can sell.
