Well ... I openly admit that HousePanel isn't designed to be polished plug and play solution. It is far easier than setting up an OpenHab solution so that isn't really a fair comparison. With that said, it does require server setup expertise or at least a willingness to learn and patiently work through the ups and downs of getting a personally hosted website on a rPi working. HP is basically just a PHP smart app that requires PHP with cURL installed and a directory setting that allows files to be written by the web user. If you make it through those three steps the rest is easy.
No hard feelings if you don't have the time or patience to work through these steps. A good alternative for you might be SharpTools which is a hosted solution and drop dead easy to set up and use. The tradeoff is it is a cloud based solution relative to what HP would give you as a local only private solution. With that said I think @josh has done an awesome job with SharpTools so I think it might be a good option for you. And I think the built-in Hubitat dashboards are a fine solution if they meet your look and feel requirements. In fact if they do what you need, I wouldn't recommend fussing with any other external dashboard at all.
Here's a recent example from a user on the SmartThings forum showing what is possible with HousePanel just so you know what you are trading off:
