I’ve did RS last year (got a 9) and I’m doing computer science currently. Personally I prefer RS 100% partly because it’s more interesting and I was good at it. To be honest I don’t see computer science being useful in the future unless you’re going into computers/technology. Something like RS can be applied to almost any workplace as you will always have people of different religions, and if you manage a team or want to get on with colleagues it’s useful to have to understand peoples thinking.
