How good it is will ultimately depend on how good a tiler you had.

However I could tell you one thing, for outdoor usage it isn't that good.

Unless it is an indoor application or an application where it is shaded from the sun this does have a tendency to develop masonry cracks and some of the earlier brick pattern ones I did are starting to discolour, red no longer seems as red as it used to be when new.

Another thing that does happen to them, unlike real facing bricks they do tend to attract a lot more algae and moss growth. Was told because it is mostly made from sand and the sand does tend to absorb some water and remain wet for longer.
