My husband and I faced the same situation when building our house 6 years ago. We didn't have kids at the time, but we expected to be there for a while. Of course, they have all kinds of discussions about redistricting, have already rezoned to different schools, and our kids are the same age as yours.
What we decided, at the end of the day, is that we wanted a fundamentally sound school system with good SAT scores, reputable schools and teachers. But, it was our responsibility to fill in any gaps we recognized. We kind of realized that too many people blame the school instead of being practive and working with their kids outside of school hours.
We haven't faced that yet, and I'm sure we'll get pretty active in things once our son starts Kindergarten next year. I went through one of the best school systems in the country, but it was my parent's constant harassment that likely made me excel to the extent I did.
Good luck.
