I say WBritain-have both new sets and they far surpass both companies in quality AND price. The sculpting is incredibly detailed, and the painting is great, and the price is in the range of $75...or 50 GBP...anyway, there are only two so far, so if I were making a similar display, I would definatly give them a chance....
I saw the Scots Grey's at the London Show and would disagree. I do not think the sculpting is as good as KC or CS; nor do I suspect they are compatible because they are smaller. As to price, at £64.99 in the UK, I do not think they represent as good value as CS.
Have a great Christmas
