In your case, proximity to you and your spouse’s office should be No1 priority.
Then, good/great school should be the second priority.
Many people say that they can send their kids to private school but the problem is good private schools (especially good private high schools) are not necessarily close to either your home or office.
Then, drop-off/pick-up becomes nightmare.
If I were you, I would go for TH in MV/SUNNYVALE/CUPERTINO(CU district).
I don’t think 1.5million is sufficient enough for PA/LA TH.
Another thing you probably want to consider is “whether or not middle/high school is within biking distance with safe bike lane from your new home”.
You can send your kids to after school program until 5th grade but from middle school, your kids probably don’t want to go to after school care although such service is available (which is very rare).
My kid bikes back home and it has been working pretty well.
As both working parents, your choice should be optimized for pick-up/drop-off schedule.
Trust me. This will really define your family’s life quality.
