I am not a fan of yarrow in general. I find it weedy and too often overrun by grass. I do, however, grow it for its herbal properties. I've tried several cultivars and have settled on this one as my go-to. The bloom color is very striking (many others seem washed out or dirty to me), it clumps up nicely, and it hopefully will spread into a solid mass. If all goes well, I will likely divide this so I have 3 groupings of it among my herbs. Nice bright spot among the mostly purple or yellow flowers of other herbs. The leaves are edible either raw or cooked, although they are bitter. Some folks may develop a skin rash from yarrow or become more sensitive to sunlight.
