6 years ago I had (I think) 5 schools with sites built with contribute, hosted with random hosting co. Most have moved to using their VLE as the school website, apart from one where there's a TA who is handy with a mouse and listened when I showed her how to do stuff. The one remaining site put together using Contribute is undoubtedly the best of the lot, my quite some margin. But that's because it is updated without fail every single week, by someone who knows and cares what shade of blue and if there's an easy way to navigate around the site and what the swimming coach will leave and which is the right version of the newsletter and about apostrophes and everything. And who gives the kids (and, I believe, the teachers) prizes if they give her web content to upload.
I reckon it doesn't matter what the technology is, all that much, tbh. Whichever they can get their head round, or if it's going to get ignored completely and never updated, whichever is cheapest.
