This is a typical landranger product. Features are mapped in the right places, and the map gives a good idea of the shape of the land.
A lot of tracks and paths are omitted, there is some debateable contouring, vast areas of crag and rocky terrain aren't indicated, and half the paths that are on the map are difficult to see because of the marking of access land boundaries. Don't the OS know that all open land in Scotland is access land anyway? Why cover the map in meaningless purple lines? If we want to know where the boundary of NTS land is, then we'll ask the NTS.
Anyway, rant aside, this is a useful product. The Outdoor Leisure Map is better for walkers and climbers, and the Harvey map is better still, in my view. You just don't get as much coverage with a 1:25,000, so you might need to buy two, rather than one 1:50,000. If the detail on the 25k map could save your life then I think that's a worthwhile investment, otherwise you'll be fine with this Landranger product.
