Not really an expert but...
Although the weight and price are the same, if you look at the geometry tables for both bikes the Corratec has a slightly longer effective top tube, slightly shorter head tube and slightly steeper head angle.
So the Corratec is more a race bike, suited for shorter, head-down fast-as-possible outings (and probably designed for power transfer above comfort)
and the Beone is a bit more trail-bike (slightly more stable on the downs, slightly more relaxed position for comfort on longer outings).
I'd buy the BeOne. The forks, brakes and drivetrain are much better and a bit more up to date (not really sure about the Manitou fork - but I bet you can get rebas serviced and fixed more easily and cheaper! Also, it looks like the BeOne has a tapered head tube but the Corratec doesn't - suggests an older design for the Corratec). That way you've got a bike that can do anything and is light enough to race, instead of a race bike with heavy components.
I bet you're going to reply saying you've bought the Corratec now aren't you!
