Hands down Top loader, I hate front loaders. I find your clothes are so crinkled when they come out. My top loader I can wash queen dooners and blankets, no way my front loader could cope with those. It also was really crap at washing my husbands dirty work clothes. I also think if you usually wash in cold then the saving comparisons are really not that great.
Oh and my back, another reason I hate front loaders. I have never had problems with my back except the time I was bending over in that stupid front loader. I was so happy to buy another top loader
