Compustat Global vs. Reuters Fundamentals vs. Thomson Worldscope

  1. I'm interested in opinions about data quality and historical availability of fundamental information (quarterly, annually) in the above mentioned databases. Anyone has experience screening companies with these databases including backtesting?

    I am currently using Compustat north america which covers 48 quarters (12 years) of fundamentals in addition to 10 years of daily market data.
