The key benefits are that we have full control over plugins, themes, code and customisations plus we are able to move or manage the site as needed, especially like the mailing list, gravity forms, visual composer, woocommerce, all these plugins which we buy developer licences for and have full access to use.

The features available with are usually included in the jetpack plugin so you get all the nice galleries, the embed codes and things like that too with a self hosted site.

Plus for many of our clients it is simply nice to have us close at hand, easy to deal with and people who you can call if you have a question.
