I personally prefer using Landrangers and always have done. I prefer the overview of the route they give and have never got seriously lost using them. Over the last two years I have used them while hiking the Pennine Way, West Highland Way, Southern Uplands, Coast to Coast and Cape Wrath Trail. I suppose it's what you are used to but I have never felt the need to switch to 1:25,000 scale and on the odd occasion that I have used them, was always glad to switch back to Landrangers.
