The master liche also has an additional misc magic item slot. It's a modest bonus, to be sure, but can save you a lot of points on the right build - if nothing else, it's notably cheaper to buy the earth levels needed for a crystal coin than it is to buy astral 6 up from 5 (since rings, skullcap give +3) and then you have earth magic to boot.

I'm willing to believe that Graeme's little finger knows more about Dominions than I do, but that at least is one possible case where master liche comes out ahead. If you want an SC chassis, the queen is obviously better (although I'd guess the Prince, though not immortal, is a much better choice than either for initial expansion needs).
