The ease of use when it comes syncing with sites like Google Analytics is great! I can add my GA code in once instead adding each tracking ID as needed for our different websites we have (2-3 per year).
Not much dislike about this product - if you're looking at something that will help keep trackings data up date between your site's platform then definitely look into using SytnonX products. We are able sync all analytics info from 3+ platforms together so no more manual entry or needing several logins/passwords just because one system requires them but not another etc..
