I feel your pain!! When we moved, my SIL was our realtor & lived in the district we were moving to. She kept telling me -it doesn't matter, all the schools are good because the district is so good. Well, I don't buy that & spent several hours/days researching all the options.
Another site I liked is greatschools.net, I paid the fee to get the full scoop. Plus I found a state website that gave a really detailed breakdown on each school. It's worth checking, I wanted to know test scores, student ratios, all that stuff.
If you really want to drive yourself nuts, think about where the elementary feed into and if they split. There were some houses that I liked the elementary but not the middle school. In our house now, our elementary splits in middle school. I don't like that because depending on where our kids' friends live, they may go to different middles but may meet back up in HS.
There are some schools here that are newer but also already overcrowded because of new developments that went up. We picked an older, smaller school & have been extremely pleased so far. Active PTO, not too many clubs but they're young enough they can do activities outside of school.
I will say I grew up in a school w/many "haves" -BMWs for 16th bday types, but many were not and we all did fine. My kids will be in the same boat but there are such good opportunities for academics, sports & activities that they will learn to deal. Good luck!!
