Hello @John613 first off thanks for being a Patron! Much appreciated.
There are multiple benefits but only one that sticks out to me. With Syncler+ you can install the Express packages which pull in more links and they are also higher quality such as 1080p and 4K.
Without Syncler+ you can only use Kosmos packages which don’t bring in as many good links. Some may disagree with this but that is what I personally notice.
