"Simply" replacing plastic with metal gutters is not necessarily going to show any improvement. Neither is it likely to be simple ! I have done a bit of this work - on the wonderful galvanized-steel gutters referred-to - and much of the problem is to organize the gutter dead level, or very slightly inclined. This involves adjusting several of the supports, often up at a height. Not a greatly enjoyable game, in metal or plastic !

Maybe I haven't grasped this properly but surely the levelling (or unlevelling issue) applies regardless of the material used. No guttering that is dead level is going to work very well but I do believe the better materials such as galvanised steel and copper are better longer term solutions, and in respect of copper will probably only need to be done once per 5 generations! SO that means 4 times less levelling...
