The way I see it is the more vigorous the oscillating agitator washers are in SPM (strokes per minute) along with the length of the oscillations they move, determines the ware and tare on the load of laundry you're washing. The type of fabric is also going to make a difference in how worn the clothes will get. For example, if you're washing a load of towels, wash cloths, and bath mats in a GE FF and the same exact load in a BD Whirlpool, there will be more lint in the filter pan then in the filter brush or pin tray. Then, as you dry them, the GE load will also have more lint then the other. Because the front loaders are a lot less vigorous and have no sharp agitator blades, the same load will leave a lot less lint in the dryer. The front loaders have a trap but it's made mostly to catch loose change, paper clips, hair pins, etc. to save the pump from any damage. When I clean my front loaders, there is very little, if any lint in the button catchers. When I wash bath linens, the dryer lint filter has a real narrow line of lint,. Usually easier to remove after a few more loads are dried. Not a fat line of lint like my old DD Kenmores or GM Frigidaires had. My clothes smell cleaner and last longer too.
