What's more expensive, Chicago or Boston?

I'm curious to know, which of these two great American cities carries a higher price tag for its residents? When it comes to the cost of living, is it the bustling metropolis of Chicago with its towering skyscrapers and vibrant nightlife, or the historic and prestigious Boston, known for its world-class universities and rich cultural heritage? Both offer unique experiences and attractions, but which one demands a heavier financial commitment from those who call it home?
