It doesn't matter with all the traffic it's an hour drive from either and Midway is only served by southwest and delta no other airlines land at Midway. southwest doesn't fly into O'Hare unless your on southwest your landing at O'Hare so it doesn't matter. Take an Uber it's way faster and cheaper than a cab.
