Hi Al: I often use a "stress test" image that contains a color wheel and varying levels of transparency. I tried a couple of the sites and the outcomes were pretty similar. For myself, I'd rather use a tool that will batch process files locally and produce decent results, which ImageOptim seems to do. It's possible one of those sites might save a few more bytes here or there, but as there already aren't enough hours in the day, I'd rather spend my time solving other issues in my apps :-)
Thanks for pointing out the additional optimizing options.
