It depends if you are a more technical guy and you can manage things without a control panel you can go with plain OpenLiteSpeed image because it does not contain Mail Server and other stuff that you might not need.
However, both runs OpenLiteSpeed on the backend, with CyberPanel it will be easy for you to manage things and will save you more time.
Apart from that, you can also disable services that you won’t need on CyberPanel giving you the same performance as the plain image.
