We have a comparison chart online for UltimateWB and Wix (and other website builders): https://www.ultimatewb.com/website-builder-comparison-chart .

Please also check out the blog posts on Wix: https://www.ultimatewb.com/blog/?s=wix 

Here are some quick major differences between Wix and UltimateWB:

-UltimateWB has more built-in features.

-UltimateWB is more flexible and customizable.

-UltimateWB will cost you less.

-You get web hosting flexibility with UltimateWB, not Wix - on Wix, your website is tied to your Wix account, and once you stop paying for your web hosting, your website is offline and you cannot switch web hosts. With UltimateWB, you can host your website on any compatible server (server requirements: https://www.ultimatewb.com/server-requirements) and backup your files when using UltimateWB hosting. If you go with an UltimateWB Cloud plan first, you can choose to buy the website builder and web hosting, to have that server flexibility. So, you are not stuck with UltimateWB web hosting, but we do have great plans: free traffic statistics, SSL, and custom email.

Please feel free to ask any other questions you have, or you need help in deciding what software/hosting plan/Cloud plan to choose.
