Buffalo or Chicago: where should I spend more time?

I am driving from MA to visit my older brother in San Diego. I am planning to use I-90 west for the first portion of my trip and time is not a factor.

I plan to stop in either Buffalo, NY or Chicago, IL and I need to know which city is more interesting?

Welcome to the RTA Forum!

Asking which city is more interesting, Buffalo or Chicago is a bit like asking, which city is more interesting: Newark or New York, Hartford or Boston, Los Angeles or Sacramento?

Chicago has some of the world's finest museums, restaurants, parks, shopping, and of course skyscrapers. The Windy City is one of the most dynamic cities in North America, with New York and maybe Toronto being the only two cities that even compare.

I've got nothing against Buffalo, but I just can't see how anyone would think its more interesting than Chicago.
