I can't answer your question directly, but the modern 737 is a 2010s aircraft forced into a 1965 design. Many, many problematic design decisions have been visited upon the low-rise airframe, and many critics of the plane think the 737s should have been retired long ago in favor of a new narrow-body aircraft. I don't think those kinds of design problems are present in the 777, which was a new design from the ground up.
