I prefer these dice a lot more than the cluttered forbidden lands dice, or the new Y0 dice. The simple colors are also a plus, the forbidden lands black and red/brown dice mess with my sight and I have a hard time separating them unless in great lighting condition.
A matter of taste of course, if youre looking to make custom dice I can not recommend Chessex enough! Bought a bunch of custom dice for Arkham Horror from them and thought it to be fairly priced. And just superb customer service!
