ECON 425 or 440 for econ elective class?

Hi all! Currently planning my fall semester schedule and need one more econ course at the 400 level to complete, I'm going to have a pretty work-intensive schedule so I'd prefer an easier elective course, does anyone have any insight on if ECON 425 with C. Roark or ECON 440 with Q. Gong would be a lighter class? Any insight is much appreciated, thanks!
