There's a lot of Bs and Cs in the Valley too. Techstars is arguably an A and they're in Boulder. I'm not sure about accelerators outside of the US. But yea generally I'd say anyone is B at best until proven otherwise. The distribution of successful accelerators is likely similar to that of successful startups.

Rocket Internet in Berlin is IMHO also an A but with a questionable business model.
