On grades, well, a "distinction" (75%) is about as rare as an A in America, with very few reaching a "high distinction" (85%). Where I graduated, you'd be considered doing well just to get 70+, and 75% average is first class.

Lol, my experience with getting a job. Had a very good degree too, top 3 within the region. But in electrical engineering, with lots of programming electives.
Though the good degrees actually help a lot, go for the kind where you're forced to program virtual memory for an O/S within 2 weeks, parallel to 3 other similar assignments

And the big benefit with degrees is that they teach you to program
properly. Self-taught, you can do things, but you don't have any metric to compare yourself against other programmers. You won't know if you've been doing things wrong. I did C programming for 4 years without knowing about memory management, and C++ programming without knowing anything about how OOP works (aside from classes). Took a proper education to actually know what I was doing wrong.
Choosing not to go to college involves constantly being asked "why?" by people who are brainwashed into thinking college is the only path to success.
One generation ago, the only way to really learn something was through college. No internet resources. University gave you
lectures, not
teaching you things. The lecturer was similar to a youtube video, no real student-lecturer communication. Things have really changed in 20 years; these days you can learn a hell lot just by idly reading Stack Overflow or Wikipedia (or TV Tropes if you're into the creative arts).
Plus the true purpose of a degree is to 'certify' that you've got basic knowledge in the field.
