It's not clear exactly what you're looking at on FamilySearch. Perhaps you could provide a link in your reply or update the original post? I (and scores of others) have found FamilySearch is typically excellent for reviewing sources and seeing documents online without needing to have a paid membership to anything. The various individual family trees, though, (which might be what you are looking at) vary vastly in quality (and are often not sourced, even though many of the sources are "right there"). This is the same as is seen on other online family tree platforms ... and where WikiTree seeks to be ultra-different.
