I would get a FL washer with a heater
hands down. the heater on my duet kicks on on heavy duty, whitest whites, and sanitary cycles. It gets so hot the outside of the machine feels like a dishwasher that has been running for a long time....gets clothes super clean. I still can't believe I've made it 12 years with this thing and it still works. Based off that alone I would get a whirlpool - maytag or something made by WP, but if a TL washer, I'd get a Speed Queen...
Some people recommend LG's as the best FL washer - though I think they are all pretty good as long as they use a heater and have some cycles that use more water than others.
