There were and are a lot of web building sites besides Weebly, but weebly is the cleanest for its price by far. When I talk with small business owners I always recommend Weebly (unless I think they can do a lot of e-Commerce, in which case I recommend shopify). Weebly is the least frustrating and out of the box prettiest of the free web options.
I switched to Weebly after trying out Shopify. My problem with Shopify is that they nickel and dime you for every little thing you might need and Weebly was a lot easier to get going with I thought. My perspective might change as I grow but to start out it was pretty much a no brainier.
I created a Weebly site for the first time this week. The website quality per unit-time invested has trumped any other source I've used. After a couple of hours of designing and tweaking, it's beyond minimum-viable status, and will probably persist almost unchanged for months.

The real test of the service will be sites that require constant changing (due to SEO rewards for timely updates as much as upgrades or general content management). When I hear "probably persist almost unchanged for months" I assume you are not in a position to benefit from marketing communication.
