My personal experience / opinion: High school was boring as hell. I didn't graduate early, but the last year really started to feel a bit like torture - I was ecstatic to finally be done. University was infinitely more enjoyable, and felt like it ended too quickly. However, some of the strongest bonds I have were made during high school. Relationship-wise, in retrospect, high school was depth, while university was breadth. Not rushing high school also allowed me to do well enough to attend university for free, without ever having to worry about my workload during high school. Overall, I guess it didn't hurt me to graduate HS on time. Now for the advice part: if you want to save one year so you can graduate from university faster, don't bother. Life is short, but youth is the best part anyway... a rush towards some nebulous idea of adulthood is pointless, it'll come sooner than you want anyway. If you want to use the extra year to explore more courses in university, or to use it towards a graduate degree, or even to travel for a year - that might be worth it.
