well i am speaking about the jedi order that used to be during the Mandalorian Wars and the one on the Clone Wars . they both had their heroes who became villains ...
e.g: revan and Anakin Skaywalker ,
once upon the time Kreia said that the old sith-jedi used to be powerful and that a jedi from this age would be like a child holding a lightsaber...
so i believe that the old jedi order is stronger because it survived the The Great Hyperspace War,The Old Sith Wars,The Great Sith War,The Mandalorian Wars,
the new jedi didn't even survived the clone wars , so let the force guide you hand and express you opinions ...
