Which UK accent do you love and which do you dislike?

For me it's not so much dislike but I have trouble understanding Scottish accents, but I expect the Scots have the same trouble understanding my Norfolk accent.

My daughter use to imitate accents and would do a  Brummie accent quite well, in the middle of a supermarket she would suddenly burst into a Brummie accent just to embarrass me  sp0
