I've recently acquired a Semogue 610 and a Semogue Owners' Club, and I've been very pleased with them both. Not sure about the availability of Semogue brushes in the UK, but it's worth checking. Boar brushes are generally much cheaper than badger, and Omega and Semogue seem to be competitively priced. Some say that Semogue brushes hold up better, but each of them seem to have a pretty faithful following. I guess it probably comes down to which is the most readily available to you and then whatever your eye or gut tells you. Good Luck!
