When it comes to careers and skills, DU is definitely better. Your Sim teen will pick up minimal skills and have to attend class to gain them if you get HSY. On the other hand, I personally prefer Prom and the Amusement rides to ping-pong and keggers.
I would recommend getting both, however. If your teen gets an A in high school and level 4 in 2 skills (I think), they can graduate early and start university while still a teen. Both packs have good clothing for teens and YAs. HSY probably has the better Build/Buy catalog.
Hope this helps.
MVWdeZTThanks for these thoughts. It hadn't occurred to me (and wasn't obvious) that teens would build skills in High School Years, so this helps!
