The best things about Hyax are that it is super easy to get your site up and running. Kevin (one of the developers) is super responsive and helpful. Hyax has a faster store speed than Shopify. Jax sends weekly emails which include advice on how to grow your platform or new tools from Hyax.

The ease of use and overall UI is awe-inspiring. Also, it works well for gated content. I am sure other features are pretty decent too.
