As someone whose fought most osw clans I would put them in the following order (note I only know late 2010 onwards) :- Black Hand - in their prime were feared by everyone. A well organised stripping machine. IG - was never as big as Zaft but had a more ruthless reputation and were scary for a period, New Age, Resilience, Kotfe, CR - longevity and never back down attitude. Yafi - whilst they never cf, they were pretty dull to war for most of their time. They had a short spell around the time they merged as pretty impressive Zaft - dominant and powerful for a long time but never felt they were as ruthless as BH or IG in their prime I was part of AAH in its prime so cannot really comment as to what it was like - that's for others. Others such as LOA, ISS, Voodoo had a good period for a time. Cheers
