I was using others with not very good results and decide to buy this one even reading some bad reviews.
My experience has been very good not a single problem with it worked perfect in my website and in Blaze position has already a score of 97 what is lots better of what i had with my past ones.
Nothing more to add not going to try the agressive one as i don't need it.
You can setup some stuff but for the ones that don't have much clue about how cache works this one is your plugin will get more codes for sure for other websites.
