Klevu Theme vs Magento Theme

I have 2 questions about Klevu.

1. Can someone provide a list of pros and cons in using the Klevu theme versus Magento theme?

2. Would anyone be willing to share a URL to the website so I can understand and view how you have set up your UX?

We are going through a Klevu implementation, and I’m not so happy about some of the things I’m seeing. I’d like to view a more established company and see what they’ve done, and even what customizations are possible to make it perform better.
