Our church re-vamped our website last year with Finalweb 2.0. We had Finalweb 1.0, and our website was in dire need of an upgrade. We didn't even look at other options, but there aren't many complaints that I have with
Finalweb.
They answer your emails or calls very quickly, and their developers even added some brand new items that I requested and had seen in other website building programs. Finalweb isn't a big-name company so they are a little limited in a few aspects, and it isn't as simple to run as Squarespace or Wix is, but you can make your website how you want it with the plethora of layouts, themes, preferences, and settings. They are also really good at implementing videos from outside sources (like Vimeo or Youtube) along with a solid live stream service embedded in the website.
I know that there are other options that are really good as well in conversation with some other churches and schools that have redone their website.
Squarespace,
Wix,
Clover sites, are some other churches that I know use.
As Pastor Daley said, the greatest issue is keeping it updated. Here is our church and school's website if you want to check it out. (

I hope that this helped.
God's Blessings on your search,
