Several reasons: we're not very good with track in the US, because we've spent decades thinking primarily of freight trains and because we take the lowest bidder rather than being able to select the company with experience (this was a national scandal on the CTA O'Hare Extension back in the 1980s).
Then, CTA cars are basically lightweight streetcars running at 55 mph. They don't weigh much, and have short wheelbases. By contrast, Metra bi-levels are topheavy, so they sway quite a bit any time the two rails aren't perfectly aligned.
