Chris Boardman has lent his name to this English brand made in Asia. Specialized is an America brand made in Asia. You'll likely not be able to discern any difference in the components. All things being equal, the carbon fork might get a slight nod. You should ride before you buy. I imagine the warranties are similar, but you should check. For me, you're really buying the bike shop more than the bike, so look around. Across any given price point, the differences in ride quality, assuming identical frameset material/geometry, are so minute that once you're sure that it will fit properly, you should buy the one that looks best to you. After all, you'll be the one that has to stare at it for years, so it better be pleasing to your eye. Unless the aesthetic is meaningless to you, in which case it doesn't matter which one you buy.
