It depends on your skills/needs.
Do you want to customize everything with ease? Do you have someone who can maintain the security of your blog and eventually add new features later? => WordPress on your own hosting
Do you want to use a very classical theme? Do you want a complete service with no skills required and no maintenance? => Wix or WordPress.com
Do you want to customize everything? Do you have someone to maintain the blog on a regular base? => Jekyll on GitHub or on your own hosting
Shall you need to sell things online with the blog, WordPress can be augmented with Shopify, meanwhile Wix has already this feature.
