Tons of forms want this for obscure purposes, if in doubt I pick UM. The history of UK vs. GB is explained in RFC 3071 - for unrelated reasons I read it yesterday again. Obviously one country should have one code, and as far as that that code is mnemonic it should depend on the name of the country. In theory "united kingdom" can be less persistent - in various countries that's not only a theory.
