Here is some fire for the most ridiculous context of which tzadikim are more tzedek:
students of Chofetz Chaim were learning Mishna Berura and found a reference to a sefer that was not in the yeshiva. They went to the Rav’s house and asked him to loan them this sefer. Rav did not have it at home, but said someone in another town, just an hour on a train, has it. Students were stunned – Rebbe, you are quoting this sefer and you do not have it at home to learn? Yes, he said, it will cost money and gelt ist tzait and tzait is Toirah…
To contrast, R Ovadia lived in a small apartment and worked there. People who were in the apartment testified that he does not own numerous books that he is quoting and is doing it frmo memory, without taking the train.
