I play with them all. I think children and teens helped to definitely got more rounded with the parenthood pack along with more things in the kids room stuff pack for children as well. The void critter game that came with KR stuff is good. Since my sims can go searching in trash cans for booster packs and cards can even upgrade the cards to get their void critter stronger. With Seasons and GF they're getting more after school activities (can't wait to see more come). I always work on my children's skills to try and max them out because it does benefit them when they get older.
Younger sims like toddlers and children are always going to be limited in terms of what adults can do always has been in every game. (Way worse in the first sims game as kids didn't have much of anything to do.)
I make use of the get together club system. Having study/homework groups, playing video games at their local arcade as well as skating. And kids can even make their own videos with the GF video station which is pretty cool to me that they're able to use things like that.
I always welcome more things for teens and children alike any day of the week. Especially in terms of hobbies.
