With regard to Torrey Highlands, I’d recommend what’s north of the 56. The four developments to the south have no real ammenities–there’s a couple of dog parks, but that’s about it.
It’s bounded on one end by section 8 housing (but at least they have a playground!) and on the the other by the four large office buildings. Being close to employment is certainly nice, but being directly adjacent to it ain’t so great.
