First of all, judging from their names in the Jianghu, Bai Zhantang's "stealing saints" is not as famous as Chu Liuxiang's "stealing handsome", and "stealing saints" doesn't sound as imposing as "stealing handsome".
Secondly, judging from the origin of these two titles, Bai Zhantang himself said that this title was just that the people in the imperial court were too incompetent to catch the prisoners. In order to push the responsibility of those cases down, they put all those things on Bai Zhantang's head, and spread the story bigger and bigger. Finally, Jianghu people gave him the title of stealing saints. In fact, Bai Zhantang really didn't do anything great. Chu Liuxiang's "stealing handsome" is different. There are too many titles. Chu Liuxiang spelled it out step by step, and nothing is empty.
Finally, judging from their kung fu, Bai Zhantang came from the Sunflower School, and he knew from Wulin legends that it was not a powerful sect, otherwise it would not fall apart. Chu Liuxiang, who studied under Xiao Li, is also a famous figure in the Jianghu. As far as Chu Liuxiang himself is concerned, he is not only at the peak of flying technology, but also excellent in acupuncturing, shrinking bones and snapping fingers, reaching the level of a first-class master.
To sum up, Chu Liuxiang is worse and has disappeared without a trace.
