I got one of these recently, and while I'm not mad keen on the shield shaped castle, there are certainly lots of accessories included, and it makes a great playset.
As Andrew said, the blue/yellow quartering on two of the figures is far more realistic than most offerings, and I like them greatly for that reason. The Wolf Knights are a welcome addition to one of my clans, and that round shield is great.
If the accessories from this set were swopped with those from set 5863, there's no doubt what I'd buy, as the castle part in that set is much nicer to my eye, but I prefer these figures.
