Fair call and as I said before, you have the experience I don't. But I left school at 17, three years uni, 20 years old. That's not that far behind people and from what I can see the three years can be down to luck (not getting the progression in GA) as much as the degree.
I had a great time at uni, which I probably would have with any degree, met lots of people, who I still use as contacts today, and grew up a lot as it meant for me moving out of home. The life experience not so much the classes were beneficial.
It really is a personal thing though and I don't deny that I may have delayed my entry to an airline/captains seat/top pay grade by up to three years. It's a bit like the advice people give here of avoiding shiny jet syndrome and enjoying GA, the journey can be as important as the destination.
