PEOPLE FROM CHICAGO....help me pick a new race

Ok, so I'm over the fact that the Utah Half Ironman isn't happening this year. In fact, I've got a new challenge that I was wondering is I could get a little feedback on. My uncle in Chicago offered to fly me out there to do a race with him. He gave me three options: the Lake Geneva international distance triathlon (http://www.lakegenevasports.com/tri.html), the Lake Zurich international distance tri (http://www.lzarea.org/lztri), or the Chigago tri, also olympic distance (http://www.chicagotriathlon.com/). Has anyone from chicago raced these? any comments? Anything at all would help.
