I've been using JPEGmini Pro for the past few days. Man, I cannot believe that Adobe hasn't bought this company up yet and fully integrated it into their Creative Cloud services. JPEGmini Pro is amazing. It works so much better than 'Save For Web' and ultimately does its job of compressing the filesize of an image without sacrificing image quality. I've done comparisons between this and other image save options and I genuinely cannot tell.
