Agreed on the horror of flying a 737 several legs a day til you retire in a system that requires you to turn airplanes fast, fly fast, and pick up extra trips in order to get paid well. I'd rather have the option of wide body flying, 1 leg 20 or so days off a month.
I guess that comes down to personal preference. I like that AA allows you the choice to fly narrow or wide body (when you can hold it), intl or domestic
