I guess Stevens bikes are not really famous outside West Europe. They are German brand assembled in Hamburg, founded 27 years ago. This is everything I know about them.
Here the choice is more or less - should I go with a famous brand (at least for me) like Cannondale, Scott, etc. or no.
I can imagine that it won't matter much for me coz it will be my first race/road bike so I doubt I won't like it whatever I get.
