As you said "all three are beautiful towns". And, as Jeff said, as realtors we are careful to not say some aspect of a town is better or worse than another. It all comes down to a matter of your personal preferances. We do, however, have a wealth of information that we can point you to so that you can learn more about the communities and schools that interest you. And, of course the realtor you choose to work with can certainly take you around each town and show you where everything in those towns are located. Most of us tend to know particularly well perhaps at least about a dozen towns surrounding the towns our respective offices and/or homes are located. Personally, I happen to have lived in Wethersfield for over a couple of decades; lived in Newington before that; yet keep an office in the town of Glastonbury (which is directly across the river from Wethersfield and Rocky Hill).
Back to learning more about the communities and schools that interest you. There is a wealth of information we assemble, so feel free to take advantage of community and school information in snap-shot report forms. Click on our site listed below if you like and you will find a long list of topics under the Buying Your Home tab in the community and school information areas, including content about demographics, family attractions, cultural attractions, and transportation among others. The Snap-Shot Reports there will give you statistics on schools including location, student-teacher ratio, and students per class. The statistics on communities include data on average age, and average earnings. Click on the links that are of interest and find the information that matters to you!
Best wishes for your pending move up to our area!
