I've been using Strikingly forever, and I've been recommending it to everyone I know. It's by far the easiest tool to set up a simple website - landing page, business page, show off a product, etc. The designs are great, modern, and mobile-optimized. I've always had headaches with other website builders like Wix because they are difficult to use - Strikingly really nailed it.
Pros: the site itself is very usable. It's very easy to get a website up and running and have it look good. They actually do live up to their claims about gorgeous mobile optimized sites in minutes.
Cons: A lot of the customization features require paying, but I feel like their packages are overpriced for the needs of people who want just a personal site.
