So those others, I'd rather just categorize without names. Google knows them. And it's just my internal ranking as I searched around, nothing more. It's fresh in my mind because I recently needed to create some sites and had decided it was finally online or nothing.
Ditching my own $$ development tool, I signed up for many trials, and was getting depressed. Tools were limited, painful to navigate and use, including my own registrar and hosting vendor.
I tried to build a quick and dirty site in each one I signed up for. It was a good exercise that often ended in frustration. After a while I signed up for Wix, and it was right away a lot more what I wanted. Certainly different strengths than my desktop tool, but it has a community and is dynamically improving, had a social and SEO component I wanted, and I think actually made some attractive sites in the end. It's also nice to use. Of course I could add things but it's the best I've found yet. I'd love to find something "better", I don't have an allegiance to any one.
But back to the 'others'; To me they fell into groups like this. One type is the template driven site that allows you to modify text, pictures, and colors, period. Then ones with more flexibility in object placement and properties, including proprietary, perhaps extra cost add-ins, plus decent templates. Then Wix and (others) use a modern object based free-form or templated format. Best - Wix has has a growing proprietary and 3rd party app and services pool that can easily add some cool functions - that otherwise would need manually put into the html, and actually that's easy too.
