It’s all pretty standard suburbia. Your dollar goes a bit further in CMR. On the other hand, PQ generally has bigger backyards.
The commute to UCSD via 56 would be only slightly longer from CMR.
I think that PQ is preferable for raising a family. CMR is interspersed with a big golf course, which is nice to look at but not kid-friendly. It sucks when your house is next to a big green field with asphalt walkways, but your older kids can’t play in that field, and you can’t go for a walk with a stroller. I’d take a park with a playground over a golf course any day of the week.
I like Park Village area of PQ, but it’s rather expensive. Nice houses go for more than 600k.
